  3. Evolutions of Advanced Stamping CAE — Technology Adventures and Business Impact on Automotive Dies and Stamping

    NASA Astrophysics Data System (ADS)

    Wang, Chuantao (C. T.)

    2005-08-01

    In the past decade, sheet metal forming and die development has been transformed to a science-based and technology-driven engineering and manufacturing enterprise from a tryout-based craft. Stamping CAE, especially the sheet metal forming simulation, as one of the core components in digital die making and digital stamping, has played a key role in this historical transition. The stamping simulation technology and its industrial applications have greatly impacted automotive sheet metal product design, die developments, die construction and tryout, and production stamping. The stamping CAE community has successfully resolved the traditional formability problems such as splits and wrinkles. The evolution of the stamping CAE technology and business demands opens even greater opportunities and challenges to stamping CAE community in the areas of (1) continuously improving simulation accuracy, drastically reducing simulation time-in-system, and improving operationalability (friendliness), (2) resolving those historically difficult-to-resolve problems such as dimensional quality problems (springback and twist) and surface quality problems (distortion and skid/impact lines), (3) resolving total manufacturability problems in line die operations including blanking, draw/redraw, trim/piercing, and flanging, and (4) overcoming new problems in forming new sheet materials with new forming techniques. In this article, the author first provides an overview of the stamping CAE technology adventures and achievements, and industrial applications in the past decade. Then the author presents a summary of increasing manufacturability needs from the formability to total quality and total manufacturability of sheet metal stampings. Finally, the paper outlines the new needs and trends for continuous improvements and innovations to meet increasing challenges in line die formability and quality requirements in automotive stamping.

  4. Impact of Simulation Technology on Die and Stamping Business

    Stevens, Mark W.

    2005-08-01

    Over the last ten years, we have seen an explosion in the use of simulation-based techniques to improve the engineering, construction, and operation of GM production tools. The impact has been as profound as the overall switch to CAD/CAM from the old manual design and construction methods. The changeover to N/C machining from duplicating milling machines brought advances in accuracy and speed to our construction activity. It also brought significant reductions in fitting sculptured surfaces. Changing over to CAD design brought similar advances in accuracy, and today's use of solid modeling has enhanced that accuracy gain while finally leading to the reduction in lead time and cost through the development of parametric techniques. Elimination of paper drawings for die design, along with the process of blueprinting and distribution, provided the savings required to install high capacity computer servers, high-speed data transmission lines and integrated networks. These historic changes in the application of CAE technology in manufacturing engineering paved the way for the implementation of simulation to all aspects of our business. The benefits are being realized now, and the future holds even greater promise as the simulation techniques mature and expand. Every new line of dies is verified prior to casting for interference free operation. Sheet metal forming simulation validates the material flow, eliminating the high costs of physical experimentation dependent on trial and error methods of the past. Integrated forming simulation and die structural analysis and optimization has led to a reduction in die size and weight on the order of 30% or more. The latest techniques in factory simulation enable analysis of automated press lines, including all stamping operations with corresponding automation. This leads to manufacturing lines capable of running at higher levels of throughput, with actual results providing the capability of two or more additional strokes per minute. As we spread these simulation techniques to the balance of our business, from blank de-stacking to the racking of parts, we anticipate continued reduction in lead-time and engineering expense while improving quality and start-up execution. The author will provide an overview of technology and business evolution of the math-based process that brought an historical transition and revitalization to the die and stamping industry in the past decade. Finally, the author will give an outlook for future business needs and technology development directions.

  5. Sheet metal stamping die design for warm forming

    Ghosh, Amit K. (Ann Arbor, MI)

    2003-04-22

    In metal stamping dies, by taking advantage of improved material flow by selectively warming the die, flat sections of the die can contribute to the flow of material throughout the workpiece. Local surface heating can be accomplished by placing a heating block in the die. Distribution of heating at the flat lower train central regions outside of the bend region allows a softer flow at a lower stress to enable material flow into the thinner, higher strain areas at the bend/s. The heating block is inserted into the die and is powered by a power supply.

    Yin, Shaohui; Ohmori, Hitoshi; Uehara, Yoshihiro; Chen, Fengjun; Zhu, Yongjian; Wang, Yu

    2009-05-01

    This paper presents a ultra-precision manufacturing process of large stamping dies with confocal paraboloidal and hyperboloidal surfaces of Wolter mirror for an X-ray telescope. In order to improve the alignment of the two substrates and reduce the degeneration in imaging quality, two compound reflectors were formed from one thin substrate utilizing synthetic ELID grinding and arc-enveloped grinding method. Because the thin foil substrate was obtained by press forming, large stamping dies of foil substrate must be machined with high Fig. error and low roughness. In this ELID arc-enveloped grinding system, cast iron fiber bonded (CIFB) diamond wheels were 3-dimentional controlled to scan the workpiece and generate required surfaces. Through truing grinding wheel and ELID grinding for upper concave and lower convex stamping dies, attainable form accuracy, surface roughness were investigated.

    2014-07-01

    An integration of computer aided design (CAD), computer aided process planning (CAPP) and computer aided manufacturing (CAM) is required for development of an intelligent system to design and manufacture stamping dies in sheet metal industries. In this paper, a framework for development of an intelligent system for design and manufacturing of stamping dies is proposed. In the proposed framework, the intelligent system is structured in form of various expert system modules for different activities of design and manufacturing of dies. All system modules are integrated with each other. The proposed system takes its input in form of a CAD file of sheet metal part, and then system modules automate all tasks related to design and manufacturing of stamping dies. Modules are coded using Visual Basic (VB) and developed on the platform of AutoCAD software.

  10. Solution of boundary heat transfer coefficients between hot stamping die and cooling water based on FEM and optimization method

    2015-06-01

    The thermal physical parameters have significant effects on the calculation accuracy of physical fields, and the boundary heat transfer coefficient between the die and water is one of the most important thermal physical parameters in the hot stamping. In order to attain the boundary heat transfer coefficient, the testing devices and test procedures are designed according to the characteristic of heat transfer in the hot stamping die. A method of estimating the temperature-dependent boundary heat transfer coefficient is presented, and an inverse heat conduction software is developed based on finite element method, advance-retreat method and golden section method. The software is used to calculate the boundary heat transfer coefficient according to the temperatures measured by NiCr-NiSi thermocouples in the experiment. The research results show that, the convergence of the method given in the paper is well, the surface temperature of sample has a significant effect on the boundary heat transfer coefficient between the die and water. The boundary heat transfer coefficient increases as the surface temperature of sample reduces, and the variation is nonlinear.

    NASA Astrophysics Data System (ADS)

    Hou, M.; Friedrich, K.

    1994-03-01

    In this investigation a mould with hemispherical cavity and 80 kN hydraulic press, allowing variable stamping speeds, are employed for experimentally studying of the 3-D stamp forming process of continuous fiber reinforced thermoplastic laminates. In particular, glass fiber (GF) reinforced polyetherimide (PEI) woven fabric made of sheath surrounded, polymer powder impregnated fiber bundles manufactured by Enichem, Italy, is used. Pre-consolidated laminates are heated by contact heating in an external heater up to about 120°C above the glass transition temperature ( T g) of the polymer matrix; they are then stamp formed in a cold matched metal tool. Typical cycle times (including preheating time of the preconsolidated laminates) are in the range of 3 min. Useful processing conditions, such as stamping temperature, stamping velocity and hold-down pressure required for stamp forming of this composite are determined. In addition the effect of die geometries (deformation radian) and original laminate dimensions are studied. The results describe the correlations between processing parameters and fiber buckling. Finally the thickness distribution in stamped parts are investigated in relation to different directions of fiber orientation.

  13. Developments in Die Pressing Strategies for Low-Cost Titanium Powders

    Hovanski, Yuri; Weil, K. Scott; Lavender, Curt A.

    2009-05-01

    Recent developments in the production of low-cost titanium powders have rejuvenated interest in manufacturing titanium powder metallurgy components by direct press and sinter techniques. However excessive friction typically observed during titanium powder pressing operations leads to numerous problems ranging from non-homogeneous green densities of the compacted powder to excessive part ejection forces and reduced die life due to wear and galling. An instrumented double-acting die press was developed to both investigate the mechanics of titanium powder pressing (particularly for the new low-cost powder morphologies) and to screen potential lubricants that could reduce frictional effects. As will be discussed, the instrument was used to determine friction coefficients and to evaluate a number of candidate lubricants. These results were then used to optimize the lubricant system to reduce die-wall stresses and improve part density uniformity.

  14. Evaluation of the Pressing Characteristics of Commercially Pure Titanium Using an Instrumented Double Acting Die

    SciTech Connect

    Hovanski, Yuri; Lavender, Curt A.; Weil, K. Scott

    2008-06-19

    With recent advances in synthesizing titanium powder by low-cost routes, there has been growing interest in identifying process/material conditions that overcome the powder compaction problems typically found with this reactive metal. The use of instrumented dies in studying the cold pressing process for commercial iron and steel powders has provided greater insight into the complex phenomena that occur and may be used to evaluate constitutive relations that describe the compaction process. Nevertheless, little work has been conducted on the special, more problematic case of reactive metal powders such as titanium. An instrumented die was developed that allows die wall friction to be characterized and the radial stress distribution along the die wall and throughout the compact to be monitored. As will be presented, this tool has been used to investigate titanium compaction and to draw comparisons with results obtained on a baseline commercial iron powder. Both sets of data were systematically collected using various powder/die lubrication combinations.

    2014-06-01

    The effects of copper particles dispersed into Bi1.9Sb0.1Te2.85Se0.15 nanopowders and sintered by open die pressing (ODP) have been investigated. Submicrometric copper particles were obtained by decomposing copper acetate molecules dispersed into chalcogenides nanopowders. The acetate powders were decomposed during the sintering process at 390 °C obtaining a fine dispersion of copper particles with dimensions in the order of 500 nm. Contents up to 0.2 wt.% of copper were investigated. ODP, previously introduced as a forming process for sintering and texturing p-type (Bi0.2Sb0.8)2Te3 nanopowders, has been applied to n-type chalcogenide: the mixed alloy nanopowders and copper acetate were compacted inside a metallic protective shell and fast pressed between two heated plates, keeping the composite under load for sintering. ODP processing ensures complete consolidation of nanopowders and material texturing with the basal (00 l) planes of the hexagonal crystal cell oriented parallel to the plates. The X-ray diffraction pattern shows an orientation factor, f, obtained by the Lotgering method, up to 64 %. Thermoelectric performance of the samples was measured by the Harman method in the range of 20-170 °C. Figure of merit ( ZT) behavior with temperature was improved in copper-dispersed samples showing a shift of the maximum value at higher temperatures. This effect can be mainly associated with an improvement of electrical conductivity, due to the presence of the copper particles.

    We are studying on a press forming of a 0.3-mm-thick foil in order to make advanced thin-foil substrates with a two-stage reflector for large X-ray telescopes. We press-formed one sheet of aluminum foil using a stamping die with high accuracy, and then obtained a two-stage reflector with a length of 100 mm/stage. The accuracy of its shape along the axial direction reached to 10 ?m. Since long substrate has an advantage for fabrication of large X-ray telescopes, we are making a two-stage reflector with a stage 200 mm long. The stamping die for the long substrate was processed by the ELID method. We will perform a press-forming in this summer. In order to evaluate the press-formed substrate, we have made a surface measurement system. It is possible to response to a fabrication of the substrate quickly.

    2013-07-01

    Open die pressing (ODP) at 370°C to 420°C has been employed as a straightforward forming process for sintering and texturing p-type (Bi0.2Sb0.8)2Te3 nanopowders. x-Ray diffraction pattern analysis showed that ODP samples were strongly textured, with the basal (00 l) planes of the hexagonal crystal cell oriented parallel to the pressing plates. The degree of texturing, evaluated as the orientation factor, f, by the Lotgering method, increased with decreasing final thickness of the samples. It was about f = 45% for 10-mm-thick samples and reached 70% for 2-mm-thick samples. Thermoelectric properties of ODP specimens were measured by the Harman method in the range from 20°C to 170°C. The dimensionless figure of merit, ZT, for 10-mm-thick samples was around 1 from room temperature up to 100°C.

  2. Integrated Stamping Simulation Using State Of The Art Techniques To Fulfill Quality Assessment Requirements

    NASA Astrophysics Data System (ADS)

    Ling, David; Lambriks, Marc; El Khaldi, Fouad

    2005-08-01

    The last few years have seen the use of stamping simulation evolve to the extent that it is now a mainstream activity; a core part of the press tool engineering process. Now, new requirements for the use of challenging materials like Dual phase / Complex phase steel, VHSS, and aluminum, together with more stringent quality expectations, and shorter development cycles, there is a need to assess the panel quality in a wider context, before committing to tool manufacture. The integrated approach from ESI Group allows early up-front feasibility assessment, geometry and process optimization, and detailed process validation all within one system. Rapid die design and quick forming simulation modules play an essential role in the early stages of the process. A seamless connection between simulation and geometry is a vital characteristic, with the accurate simulation being used to validate and fine tune the process in order to assess final component quality in unprecedented detail, utilizing some of the most accurate material models available today. The combination of the distributed memory processing (DMP) solver together with new cost effective cluster based compute servers provide a practical solution to the problems of `one million element' model sizes, and more sophisticated modeling methodologies become realistic for the first time. It is no longer sufficient to merely focus on the draw die, forming simulation must now consider the entire die line up. Typically, around half of forming issues arise from the draw die, so the time has now come to address the other half as well! This paper will discuss how the PAM-STAMP 2G™ integrated solution is successfully used to deliver a positive business impact, by providing virtual panel quality assessment, tolerance control, and springback compensation. The paper will also discuss how other forming processes can be accurately modeled using the new modules.

  3. Fabrication of aligned microstructures with a single elastomeric stamp

    PubMed Central

    Tien, Joe; Nelson, Celeste M.; Chen, Christopher S.

    2002-01-01

    The fabrication of complex patterns of aligned microstructures has required the use of multiple applications of lithography. Here we describe an approach for microfabrication that encodes the two-dimensional spatial information of several photomasks onto a single elastomeric stamp by mapping each photomask onto distinct heights on the surface of the stamp. Pressing the stamp against a surface collapses the topography of the stamp such that each recessed layer contacts the surface in stepwise sequence; the greater the applied pressure, the larger the area of the stamp that contacts the surface. After contact of each new layer with the surface, we use techniques of soft lithography (microcontact printing, microfluidics, and patterning through membranes) to pattern the surfaces that contact the stamp and those that do not with inorganic, organic, or living materials. Microfabrication through the use of multilevel stamps provides a promising alternative to conventional lithography for the construction of multicomponent, aligned surfaces; these structures may find use as components of microfluidic devices or biological patterns.

  8. Applying STAMP in Accident Analysis

    NASA Technical Reports Server (NTRS)

    Accident models play a critical role in accident investigation and analysis. Most traditional models are based on an underlying chain of events. These models, however, have serious limitations when used for complex, socio-technical systems. Previously, Leveson proposed a new accident model (STAMP) based on system theory. In STAMP, the basic concept is not an event but a constraint. This paper shows how STAMP can be applied to accident analysis using three different views or models of the accident process and proposes a notation for describing this process.

    2012-01-01

    This paper investigated the die-pressing and sintering behavior of the low-cost CP-Ti and Ti-6Al- 4V powders made by the Armstrong Process . The Armstrong powders have an irregular coral like, dendritic morphology, with a dendrite size of approximately 2-5 m. As-received as well as milled powders were uniaxially pressed at designated pressures up to 690 MPa to form disk samples with different aspect ratios. In the studied pressure range, an empirical powder compaction equation was applied to linearize the green density pressure relationship, and powder compaction parameters were obtained. The Armstrong Ti-64 powder exhibited a significantly higher sinterability than the CP-Ti powder. This was explained to be due to the higher diffusivity of V at the sintering temperature. The Ti-64 samples with a green density of 71.0% increased to 99.6% after sintering at 1300oC for 1 hour. An ex-situ technique was used to track the powder morphology change before and after sintering.

  12. Channel stamping lithography of thin film materials

    NASA Astrophysics Data System (ADS)

    Jewhurst, Scott A.

    Channel Stamping is a soft lithography technique that can be used to produce patterned films of inorganic and polymer materials, with feature dimensions as small as 10's of nanometers. Lithography is achieved by filling the recessed portions (channels) of a poly(dimethylsiloxane), PDMS, stamp with a solution precursor or polymer that takes on the shape and dimensions of the channels of the stamp. The solidified precursor or polymer is then transferred to a substrate by placing the stamp into contact with the substrate surface and inducing a load onto the stamp sufficient to cause the material in the channels to contact the surface and adhere. Withdrawing the load from the stamp and removing it from the substrate surface leaves a patterned film of the precursor, which may be further processed to form the desired product. Channel Stamping techniques were developed to allow patterning with a versatility rivaling photolithographic techniques, but using inexpensive wet-chemical processing. Channel Stamping was employed to fabricate silica stripes arrays for use in GaN Lateral Epitaxial Overgrowth, log-pile photonic band-gap structures, and through etch removal of the silica, microfluidic channel arrays. Embedded arrays of silica stripes in TiO2 films (anatase, rutile and epitaxial rutile) were produced using solution precursors of Ti-oxopolymers and the crystallization and epitaxy behavior investigated, demonstrating that micro and nano-scale structures may be fabricated though entirely chemical solution deposition and soft-lithography techniques. Morphological instability behaviors, which lead to failures in thin films, of the silica stripes on sapphire substrates were observed and investigated, yielding new findings about the capillary instability of patterned films and about crystallization phenomena of silica films.

  13. Stamping SERS for creatinine sensing

    Urine can be obtained easily, readily and non-invasively. The analysis of urine can provide metabolic information of the body and the condition of renal function. Creatinine is one of the major components of human urine associated with muscle metabolism. Since the content of creatinine excreted into urine is relatively constant, it is used as an internal standard to normalize water variations. Moreover, the detection of creatinine concentration in urine is important for the renal clearance test, which can monitor the filtration function of kidney and health status. In more details, kidney failure can be imminent when the creatinine concentration in urine is high. A simple device and protocol for creatinine sensing in urine samples can be valuable for point-of-care applications. We reported quantitative analysis of creatinine in urine samples by using stamping surface enhanced Raman scattering (S-SERS) technique with nanoporous gold disk (NPGD) based SERS substrate. S-SERS technique enables label-free and multiplexed molecular sensing under dry condition, while NPGD provides a robust, controllable, and high-sensitivity SERS substrate. The performance of S-SERS with NGPDs is evaluated by the detection and quantification of pure creatinine and creatinine in artificial urine within physiologically relevant concentration ranges.

    2013-12-01

    Direct drive digital servo press has been developed as the university-industry joint research and development since 1998. On the basis of this result, 4-axes direct drive digital servo press has been developed and in the market on April of 2002. This servo press is composed of 1 slide supported by 4 ball screws and each axis has linearscale measuring the position of each axis with high accuracy less than ?m order level. Each axis is controlled independently by servo motor and feedback system. This system can keep high level parallelism and high accuracy even with high eccentric load. Furthermore the 'full stroke full power' is obtained by using ball screws. Using these features, new various types of press forming and stamping have been obtained by development and production. The new stamping and forming methods are introduced and 'manufacturing' need strategy of press forming with high added value and also the future direction of press forming are also introduced.

  16. Stamping of Thin-Walled Structural Components with Magnesium Alloy AZ31 Sheets

    SciTech Connect

    Chen, F.-K.; Chang, C.-K.

    2005-08-05

    In the present study, the stamping process for manufacturing cell phone cases with magnesium alloy AZ31 sheets was studied using both the experimental approach and the finite element analysis. In order to determine the proper forming temperature and set up a fracture criterion, tensile tests and forming limit tests were first conducted to obtain the mechanical behaviors of AZ31 sheets at various elevated temperatures. The mechanical properties of Z31 sheets obtained from the experiments were then adopted in the finite element analysis to investigate the effects of the process parameters on the formability of the stamping process of cell phone cases. The finite element simulation results revealed that both the fracture and wrinkle defects could not be eliminated at the same time by adjusting blank-holder force or blank size. A drawbead design was then performed using the finite element simulations to determine the size and the location of drawbead required to suppress the wrinkle defect. An optimum stamping process, including die geometry, forming temperature, and blank dimension, was then determined for manufacturing the cell phone cases. The finite element analysis was validated by the good agreement between the simulation results and the experimental data. It confirms that the cell phone cases can be produced with magnesium alloy AZ31 sheet by the stamping process at elevated temperatures.

  4. Multiple program participation and exits from food stamps among elders.

    PubMed

    Issar, Sukriti

    2010-01-01

    This article uses population-level administrative data from Rhode Island's Food Stamp Program to examine exits from the Food Stamp Program by elders. Multivariate event history models estimate the relations of multiple program participation and the timing of eligibility reviews to the probability of exiting food stamps. Results suggest that elders who are age 65 or older and who receive both Supplemental Security Income and food stamps have a higher probability of exiting the Food Stamp Program than do elders who receive only food stamps. The timing of eligibility reviews is also found to be positively associated with the probability of exit from food stamps. This article is argued to extend conceptual models of the determinants of food stamp exits. PMID:20873021

  13. "Duck stamp" dollars reserve native prairie tracts

    USGS Publications Warehouse

    Higgins, K.F.

    1981-01-01

    Ducks and wetlands are inseparable in the prairies. Hunters know this, bird watchers know this, wildlife managers know this, and most importantly people who manage the croplands and rangelands know this. The 1,746 tracts of native prairie within these upland-wetland complexes known as Waterfowl Production Areas are not the only lands purchased with "duck stamp" dollars. Considerable acreages have also been purchased in central and southern parts of the United States to provide staging, resting, and wintering areas for waterfowl. Since 1934, when "duck stamps" were first sold, nearly 2.5 million acres of waterfowl habitats have been acquired or taken under easement within the United States with revenue from these sales. By purchasing "duck stamps", more than 2.2 million people provide over $16.5 million in annual revenue. It is certainly gratifying to know that some of the remaining native prairie remnants in the Northern Great Plains are being reserved for the future with "duck stamp" dollars.

  4. Studies on the finite element simulation in sheet metal stamping processes

    NASA Astrophysics Data System (ADS)

    Huang, Ying

    The sheet metal stamping process plays an important role in modern industry. With the ever-increasing demand for shape complexity, product quality and new materials, the traditional trial and error method for setting up a sheet metal stamping process is no longer efficient. As a result, the Finite Element Modeling (FEM) method has now been widely used. From a physical point of view, the formability and the quality of a product are influenced by several factors. The design of the product in the initial stage and the motion of the press during the production stage are two of these crucial factors. This thesis focuses on the numerical simulation for these two factors using FEM. Currently, there are a number of commercial FEM software systems available in the market. These software systems are based on an incremental FEM process that models the sheet metal stamping process in small incremental steps. Even though the incremental FEM is accurate, it is not suitable for the initial conceptual design for its needing of detailed design parameters and enormous calculation times. As a result, another type of FEM, called the inverse FEM method or one-step FEM method, has been proposed. While it is less accurate than that of the incremental method, this method requires much less computation and hence, has a great potential. However, it also faces a number of unsolved problems, which limits its application. This motivates the presented research. After the review of the basic theory of the inverse method, a new modified arc-length search method is proposed to find better initial solution. The methods to deal with the vertical walls are also discussed and presented. Then, a generalized multi-step inverse FEM method is proposed. It solves two key obstacles: the first one is to determine the initial solution of the intermediate three-dimensional configurations and the other is to control the movement of nodes so they could only slide on constraint surfaces during the search by Newton-Raphson iteration. The computer implementation of the generalized multi-step inverse FEM is also presented. By comparing to the simulation results using a commercial software system, the effectiveness of the new method is validated. Other than the product design, the punch motion (including punch speed and punch trajectory) of the stamping press also has significant effect on the formability and the quality of the product. In fact, this is one of the major reasons why hydraulic presses and/or servo presses are used for parts which demand high quality. In order to reveal the quantitative correlation between the punch motion and the part quality, the Cowper-Symonds strain rate constitutive model and the implicit dynamic incremental FEM are combined to conduct the research. The effects of the punch motion on the part quality, especially the plastic strain distribution and the potential springback, have been investigated for the deep drawing and the bending processes respectively. A qualitative relationship between the punch motion and the part quality is also derived. The reaction force of the punch motion causes the dynamic deformation of the press during the stamping, which in turn influences the part quality as well. This dynamic information, in the form of the strain signal, is an important basis for the on-line monitoring of the part quality. By using the actual force as the input to the press, the incremental FEM is needed to predict the strain of the press. The result is validated by means of experiments and can be used to assist the on-line monitoring.

    In the present study, 3-dimensional finite element analyses for hot-stamping processes of Audi B-pillar product are conducted using JSTAMP/NV and HEEDS. Special attention is paid to the optimization of simulation technology coupling with thermal-mechanical formulations. Numerical simulation based on FEM technology and optimization design using the hybrid adaptive SHERPA algorithm are applied to hot stamping operation to improve productivity. The robustness of the SHERPA algorithm is found through the results of the benchmark example. The SHERPA algorithm is shown to be far superior to the GA (Genetic Algorithm) in terms of efficiency, whose calculation time is about 7 times faster than that of the GA. The SHERPA algorithm could show high performance in a large scale problem having complicated design space and long calculation time.

    This paper presents a comparative study of the laser cleaning regimes applied to colored substrates with various chromatic characteristics, including colored paper and printed paper with different dpi (dots per inch) values. Tests are done under microscope with high precision techniques, using controlled Nd:YAG laser. The wavelength preponderantly used in the experiments is the Nd:YAG fundamental regime (1064 nm). Parallel experiments at 532 nm have been developed on difficult cases, or when the results were not satisfactory with 1064 nm. The main part of the work presents some results on stamp cleaning. Experimental results indicate that cleaning efficiency is correlated with the color of substrate, age of the ink on the stamp, color quality and paper quality.

    We describe a new method (STAMP) for characterization of pathogen population dynamics during infection. STAMP analyzes the frequency changes of genetically “barcoded” organisms to quantify population bottlenecks and infer the founding population size. Analyses of intra-intestinal Vibrio cholerae revealed infection-stage and region-specific host barriers to infection, and unexpectedly showed V. cholerae migration counter to intestinal flow. STAMP provides a robust, widely applicable analytical framework for high confidence characterization of in vivo microbial dissemination. PMID:25599549

  10. On the Determination of the Blank Shape Contour for Thin Precision Parts Obtained by Stamping

    The present study deals with the 'automatic' determination of the initial blank shape contour for 3D thin metallic precision parts obtained by stamping, knowing the 3D CAD geometry of the final part (the desired product). The forming process can involve several steps presented in this paper that consists in applying a heuristic method of optimization to find out the initial blank shape of thin precision metallic part in order to obtain a final part, with a required 3D geometry (specified). The purpose of the present approach is to replace the experimental trial and error optimization method used currently, which is expensive and time consuming. The principle of the 'heuristic' optimization method is to first estimate the blank shape using the Inverse Approach, then to compensate the shape error calculated in each node of the blank contour. The 'heuristic' optimization loop is done using a precise incremental code (Abaqus Explicit or Stampack) and, the iterations loop is stopped when the shape errors are within some initially fixed tolerances. The method is tested in the case of a special stamping process where the parts are pressed in one or more steps using a manual press, without blank holder and by the mean of tools having complex shape. The sensitivities of the process parameters regarding the optimal solution are investigated.

  20. Polymer Stamps for Imprinting Nanopatterns in Polymer Substrate.

    2015-01-01

    Using a silicone or metallic stamp for imprinting multiscale patterns comprising micro down to nanoscale patterns into polymer substrates often results in significant deformation in the molded substrate and loss of pattern transfer fidelity for nanopatterns. In the worst case, the expensive stamp can also be damaged. One method to reduce the problem is to use polymer as the stamp material, which will reduce both adhesion and thermal stress generated at the stamp/substrate interface. In this paper, stamps made of three different polymer materials, i.e., polydimethylsiloxane (PDMS), PPGDA-based UV resin and TPGDA-based UV-resin, were fabricated from the same master containing nanofluidic structures and the replication fidelity from the master, polymer stamps, to thermal-imprinted poly(methyl methacrylate) substrate (PMMA) was compared. The largest loss of pattern fidelity occurs in the thermal imprinting step. Polymer stamps with higher Young's moduli result in a better fidelity in pattern transfer. With TPGDA-based UV resin stamps, multiscale structures with a nanochannel with minimum width and height of -70 nm can be imprinted onto PMMA substrate together with macro-scale patterns by a single nanoimprinting processes.

    Time and frequency data are often transmitted over public packet-switched networks, and the use of this mode of distribution is likely to increase in the near future as high-speed logical circuits transmitted via networks replace point-to-point physical circuits. ALthough these networks have many technical advantages, they are susceptible to evesdropping, spoofing, and the alteration of messages enroute using techniques that are relatively simple to implement and quite difficult to detect. I will discuss a number of solutions to these problems, including the authentication mechanism used in the Network Time Protocol (NTP) and the more general technique of signing time-stamps using public key cryptography. This public key method can also be used to implement the digital analog of a Notary Public, and I will discuss how such a system could be realized on a public network such as the Internet.

  14. Single-layer versus two-layer stamps for reduced pressure thermal nanoimprint

    NASA Astrophysics Data System (ADS)

    Papenheim, Marc; Dhima, Khalid; Wang, Si; Steinberg, Christian; Scheer, Hella-Christin

    2015-11-01

    Low-pressure imprint is interesting to avoid stamp deformation, stamp failure as well as polymer recovery. When large-area stamps are prepared with a stepping procedure, low pressure is required to optimize the stitching. However, with low-pressure imprint, conformal contact between stamp and substrate is critical. Admittedly, the imprint pressure required for conformal contact depends on the stamp material and its thickness. To get an idea to which extent the imprint pressure can be reduced with a flexible stamp, we compared different stamp materials and stamp architectures, single-layer stamps and two-layer stamps. The two-layer stamps are replica stamps, where the structures were replicated in a thin layer of OrmoStamp, fixed by a backplane. On the background of plate theory, we deduce the pressure reduction compared to a Si stamp by calculating the respective pressure ratio, independent from geometries. In addition, temperature-induced issues are addressed which are of relevance for a thermal imprint process. These issues are related to the mismatch between the thermal expansion coefficients of the stamp and the substrate, and in case of a two-layer stamp, to the mismatch between the backplane material and the top layer. The latter results in temperature-induced stamp bending. On the basis of simple analytical calculations, the potential of single-layer stamps and two-layer stamps with respect to thermal imprint at reduced pressure is discussed and guidelines are provided to assess the imprint situation when replica stamps are used for imprint. The results demonstrate the attractiveness of two-layer stamps for reduced pressure nanoimprint, even in a temperature-based process.

    Patterning techniques are essential to many research fields such as chemistry, biology, medicine, and micro-electromechanical systems. In this letter, we report a simple, fast, and low-cost superhydrophobic patterning method using a superhydrophilic template. The technique is based on the contact stamping of the surface during hydrophobic dip coating. Surface characteristics were measured using scanning electron microscopy and energy-dispersive X-ray spectroscopic analysis. The results showed that the hydrophilic template, which was contacted with the stamp, was not affected by the hydrophobic solution. The resolution study was conducted using a stripe shaped stamp. The patterned line was linearly proportional to the width of the stamp line with a constant narrowing effect. A surface with regions of four different types of wetting was fabricated to demonstrate the patterning performance.

  19. A defects detection system for the surfaces of stampings

    NASA Astrophysics Data System (ADS)

    2013-12-01

    Detecting defects on the surfaces of stampings plays a critical role in the manufacturing process. Many methods have been proposed to detect and identify simple defects on stampings. However, these methods suffer from large system size, high cost, and low speed for inspection. This paper proposes a new visual system for detecting defects on the surfaces of stampings. A set of LED bar lights are used to illuminate the stamping surface from the four sides. This can ensure that the irradiation directions are parallel to the surface. Thus, it can enhance the imaging of the defects and punching edges in the vertical orientation of the surface, which facilitates the location of the defects such as scratch and pitting and the measurement of the punching sizes. Thereby, the defects can be classified using simple shape and dimension analysis. The proposed system is a part of the automated sorting system. Practical operations verify the effectiveness of the proposed system.

  16. Investigation of the Hot-Stamping Process for Advanced High-Strength Steel Sheet by Numerical Simulation

    NASA Astrophysics Data System (ADS)

    2010-04-01

    Hot forming is a new way to manufacture complex-shaped components of advanced high-strength steel (AHSS) sheet with a minimum of spring-back. Numerical simulation is an effective way to examine the hot-forming process, particularly to determine thermal and thermo-mechanical characteristics and their dependencies on temperature, strain and strain rate. The flow behavior of the 22MnB5 AHSS is investigated through hot tensile tests. A 3D finite element (FE) model of hot-stamping process for the [InlineMediaObject not available: see fulltext.] shaped part is built under the ABAQUS/Explicit environment based on the solutions of several key problems, such as treatment of contact between blank and tools, determination of material characteristics and meshing, etc. Numerical simulation is carried out to investigate the influence of blank holder force (BHF) and die gap on the hot-forming process for the [InlineMediaObject not available: see fulltext.] shaped part. Numerical results show the FE model is effective in simulation of hot-forming process. Large BHF reduces the amount of spring-back and improves the contact of flange with tools while avoiding cracking of stamped part. Die gap has a considerable influence on the distribution of temperature on side walls; the larger the die gap, higher is the temperature on the sidewall of [InlineMediaObject not available: see fulltext.] shaped part.

    Simpson, M.L.; Bliss, R.F.; McMillan, D.E.; Nodine, R.N.; Goddard, J.S.

    1991-12-03

    Color measurement is an important aspect of quality control for graphic printing press operation. Normally, measurements of color quality are performed by sampling the product off-line, in which case feedback to press operators is not available in a timely manner. On-press measurement of color quality provides timely feedback to the press operators; however, maintaining the accuracy of the measurement in a dynamic setting is not trivial. In this paper, a colorimeter measurement system using commercially available equipment is described for making reliable, on-press color measurements. The system was demonstrated on a web test bed running loops of printed graphic images. Examples of commercially printed graphic material include product labels, packaging, stamps, and wall paper. Resulting color measurements were shown to be highly sensitive to variations in color-content while maintaining invariance to web speeds as high as 500 ft/min. 6 refs.

    2010-03-01

    A digital time stamping system based on open source technologies (LINUX-UBUNTU, OpenTSA, OpenSSL, MySQL) is described in detail, including all important testing results. The system, called BALTICTIME, was developed under a project sponsored by the European Commission under the Program FP 6. It was designed to meet the requirements posed to the systems of legal and accountable time stamping and to be applicable to the hardware commonly used by the national time metrology laboratories. The BALTICTIME system is intended for the use of governmental and other institutions as well as personal bodies. Testing results demonstrate that the time stamps issued to the user by BALTICTIME and saved in BALTICTIME's archives (which implies that the time stamps are accountable) meet all the regulatory requirements. Moreover, the BALTICTIME in its present implementation is able to issue more than 10 digital time stamps per second. The system can be enhanced if needed. The test version of the BALTICTIME service is free and available at http://baltictime. pfi.lt:8080/btws/ and http://baltictime.lnmc.lv:8080/btws/. PMID:20211793

    Diabetes is rapidly escalating amongst low-income, older adults at great cost to the Medicare program. We use longitudinal survey data from the Health and Retirement Study linked to administrative Medicare records and biomarker data to assess the relationship between Food Stamp receipt and diabetes health outcomes. We find no significant difference in Medicare spending, outpatient utilization, diabetes hospitalizations and blood sugar (HbA1c) levels between recipients and income-eligible non-recipients after controlling for a detailed set of covariates including individual fixed effects and measures of diabetes treatment compliance. As one-third of elderly Food Stamp recipients are currently diabetic, greater coordination between the Food Stamp, Medicare, and Medicaid programs may improve health outcomes for this group.

    Stamping is one of the most effective ways to form textile composites in industry for providing high-strength, low-weight and cost-effective products. This paper presents a fully continuum mechanics-based approach for stamping simulation of textile fiber reinforced composites by using finite element (FE) method. A previously developed non-orthogonal constitutive model is used to represent the anisotropic mechanical behavior of textile composites under large deformation during stamping. Simulation are performed on a balanced plain weave composite with 0 deg./90 deg. and {+-}45 deg. as initial yarn orientation over a benchmark double dome device. Simulation results show good agreement with experimental output in terms of a number of parameters selected for comparison.

    I use changes in immigrant eligibility for food stamps under the 1996 federal law and heterogeneous state responses to set up a natural experiment research design to study the effect of food stamps on Body Mass Index (BMI) of adults in immigrant families. I find that in the post-1996 period food stamps use by foreign-born unmarried mothers with a high school or lower education was 10 percentage points higher in states with substitute programs than in states that implemented the federal ban. However, this increase in FSP participation was not associated with any statistically significant difference in BMI. I find that FSP participation was associated a statistically insignificant 0.3% increase in BMI among low-educated unmarried mothers. PMID:17382418

    1996-04-01

    Today, the PCR analysis of DNA from the saliva deposited on a stamp of an anonymous letter can lead to an identification. However, this analysis still involves problems, and DNA extraction can be particularly difficult. A comparative study of two DNA extraction methods with two categories of postage stamps was carried out and a purification process was tested. This study shows that the extraction with phenol/chloroform gives much better results than Chelex extraction. A purification process such as the use of Centricon 100 microconcentrators is recommended when an inhibition of PCR is present. This operation, however, results in a large loss of material.

  11. Energy Consumption of Die Casting Operations

    SciTech Connect

    Jerald Brevick; clark Mount-Campbell; Carroll Mobley

    2004-03-15

    Molten metal processing is inherently energy intensive and roughly 25% of the cost of die-cast products can be traced to some form of energy consumption [1]. The obvious major energy requirements are for melting and holding molten alloy in preparation for casting. The proper selection and maintenance of melting and holding equipment are clearly important factors in minimizing energy consumption in die-casting operations [2]. In addition to energy consumption, furnace selection also influences metal loss due to oxidation, metal quality, and maintenance requirements. Other important factors influencing energy consumption in a die-casting facility include geographic location, alloy(s) cast, starting form of alloy (solid or liquid), overall process flow, casting yield, scrap rate, cycle times, number of shifts per day, days of operation per month, type and size of die-casting form of alloy (solid or liquid), overall process flow, casting yield, scrap rate, cycle times, number of shifts per day, days of operation per month, type and size of die-casting machine, related equipment (robots, trim presses), and downstream processing (machining, plating, assembly, etc.). Each of these factors also may influence the casting quality and productivity of a die-casting enterprise. In a die-casting enterprise, decisions regarding these issues are made frequently and are based on a large number of factors. Therefore, it is not surprising that energy consumption can vary significantly from one die-casting enterprise to the next, and within a single enterprise as function of time.

  12. Apparatus for restraining and transporting dies

    DOEpatents

    Allison, James W. (Monroeville, PA); LaBarre, Timothy L. (Pittsburgh, PA)

    1994-01-01

    Apparatus for restraining and transporting dies in punch press operations is provided. A floatation platen for supporting a die on the platen's upper surface has a plurality of recessed gas exhaust ports on the platen's lower surface. A source of pressurized gas delivers gas to a platen manifold, for delivery to orifices located in the gas exhaust ports. The flow of gas is controlled by a first valve adjacent the gas source and a second valve adjacent the manifold, with the second valve being used to control the gas flow during movement of the die. In this fashion, a die may be moved on a cushion of air from one workstation to a selected second workstation. A moveable hydraulically operated restraining fixture is also provided, for clamping the die in position during the compacting phase, and for releasing the die after completion of the compacting phase by releasing the hydraulic pressure on the restraining fixture. When pressure in the hydraulic cylinders on the restraining fixture is reversed, the restraining fixture will retract so that there is no contact between the die and the restraining fixture, thereby allowing the die to be removed from a first workstation and moved to a second selected workstation.

    This investigation determined whether selected ion beam sputtered coatings on H-13 die steel would have the potential of improving the thermal fatigue behavior of the steel used as a die in aluminum die casting. The coatings were selected to test candidate insulators and metals capable of providing protection of the die surface. The studies indicate that 1 micrometer thick W and Pt coatings reduced the thermal fatigue more than any other coating tested and are candidates to be used on a die surface to increase die life.

  17. Impact Of The Material Variability On The Stamping Process: Numerical And Analytical Analysis

    NASA Astrophysics Data System (ADS)

    Ledoux, Yann; Sergent, Alain; Arrieux, Robert

    2007-05-01

    The finite element simulation is a very useful tool in the deep drawing industry. It is used more particularly for the development and the validation of new stamping tools. It allows to decrease cost and time for the tooling design and set up. But one of the most important difficulties to have a good agreement between the simulation and the real process comes from the definition of the numerical conditions (mesh, punch travel speed, limit conditions,…) and the parameters which model the material behavior. Indeed, in press shop, when the sheet set changes, often a variation of the formed part geometry is observed according to the variability of the material properties between these different sets. This last parameter represents probably one of the main source of process deviation when the process is set up. That's why it is important to study the influence of material data variation on the geometry of a classical stamped part. The chosen geometry is an omega shaped part because of its simplicity and it is representative one in the automotive industry (car body reinforcement). Moreover, it shows important springback deviations. An isotropic behaviour law is assumed. The impact of the statistical deviation of the three law coefficients characterizing the material and the friction coefficient around their nominal values is tested. A Gaussian distribution is supposed and their impact on the geometry variation is studied by FE simulation. An other approach is envisaged consisting in modeling the process variability by a mathematical model and then, in function of the input parameters variability, it is proposed to define an analytical model which leads to find the part geometry variability around the nominal shape. These two approaches allow to predict the process capability as a function of the material parameter variability.

  9. Improving the Accuracy of Stamping Analyses Including Springback Deformations

    An accurate prediction of sheet metal deformation including springback is one of the main issues in an efficient finite element (FE) simulation in automotive and stamping industries. Considering tooling design for newer class of high-strength steels, in particular, this requirement became an important aspect for springback compensation practices today. The sheet deformation modeling accounting Bauschinger effect is considered to be a key factor affecting the accuracy of FE simulations in this context. In this article, a rate-independent cyclic plasticity model is presented and implemented into LS-Dyna software for an accurate modeling of sheet metal deformation in stamping simulations. The proposed model uses Hill's orthotropic yield surface in the description of yield loci of planar and transversely anisotropic sheets. The strain-hardening behavior is calculated based on an additive backstress form of the nonlinear kinematic hardening rule. The proposed model is applied in stamping simulations of a dual-phase steel automotive part, and comparisons are presented in terms of part strain and thickness distributions calculated with isotropic plasticity and the proposed model. It is observed that both models produce similar plastic strain and thickness distributions; however, there appeared to be considerable differences in computed springback deformations. Part shapes computed with both plasticity models were evaluated with surface scanning of manufactured parts. A comparison of FE computed geometries with manufactured parts proved the improved performance of proposed model over isotropic plasticity for this particular stamping application.

    Replication of surface nano-structures from a master stamp allows large-area volume production that is otherwise cost prohibitive through conventional direct-write methods, such as electron beam lithography and focused ion beam milling. However, the creation of a master stamp containing sophisticated patterns still requires significant time on such direct-write tools. We demonstrate a method for reducing this tool time by patterning smaller nano-structures, and then enlarging them to the desired size through isotropic etching. We can create circular structures of any arrangement and size, down to the patterning limits of the direct-write tools. Subsequent metal mask deposition, lift-off, and anisotropic etching transforms the circular patterns to out-of-plane pillar structures for the final stamp. A 1 cm2 area filled with a pattern of 200 nm diameter nano-holes spaced 520 nm apart, requires only 21 h to complete using our process, compared to 75 h using conventional fabrication. We demonstrate the utility and practicality of the quartz stamps through polymer embossing and replication. Embossed polymer nano-hole arrays are coated with a Cr/Au (5/100 nm) film to create surface plasmon resonance structures. Extraordinary optical transmission spectra from the metallized arrays show the expected spectral features when compared to focused ion beam milled structures.

  18. Characterization of DC-STAMP+ Cells in Human Bone Marrow

    2014-01-01

    Osteoclasts (OC), specialized cells derived from monocytes, maintain skeletal homeostasis under normal conditions but degrade bone in patients with rheumatoid (RA) and psoriatic arthritis (PsA). Monocytes initially develop in the bone marrow (BM), circulate in peripheral blood, and differentiate into distinct cell types with diverse functions. Imaging studies in (RA) patients and murine arthritis models demonstrate that bone marrow edema detected on MRI is the result of enhanced myelopoiesis which precedes the development of bone erosions detected on plain radiographs several years later. A major knowledge gap, however, is whether OC develop in the BM and circulate to the joint and if the differentiation to OC takes place in the joint space in response to differentiation signals such as RANKL and TNF. We have previously demonstrated that osteoclast precursors (OCP) are increased in the circulaton of patients with RA and PsA. We showed that DC-STAMP (Dendritic Cell-Specific Transmembrane protein), a 7-pass transmembrane protein expressed on the surface of monocytes, is essential for cell-to-cell fusion during OC differentiation and is a valid biomarker of OCP. Herein, we examined OCP in human bone marrow and identified one novel subset of DC-STAMP+CD45intermediate monocytes which was absent in the blood. We also found that OCPs reside in human BM with a higher frequency than in the peripheral blood. These findings support the notion that the BM is a major reservoir of circulating OCPs. In addition, we demonstrated that a higher frequency of DC-STAMP+ cells in the BM have detectable intracellular IFN-?, IL-4 and IL-17A than DC-STAMP+ cells circulating in the peripheral blood. Finally, the frequency of DC-STAMP+ monocytes and T cells is signficantly higher in PsA BM compared to healthy controls, suggesting an enhanced myelopoiesis is a central event in inflammatory arthritis.

    The preparation of nanostructures by guiding the phase separation of a block copolymer (BCP) is an attractive technique to overcome the limitations of conventional lithography. Well-established methods for guiding are to provide a topographical pattern (grapho-epitaxy) or a chemical pattern (chemo-epitaxy) on the substrate before BCP application. This paper reports on an alternative technique, the guiding of the BCP without pre-patterning the substrate, by providing the guiding pattern from the top, by nanoimprint. This approach offers the benefit of a multiple use of the same stamp. In the work reported here, we use an elastomeric stamp and examine capillary force lithography (CFL) with respect to guiding. The processing temperature is chosen high in order to provide fast phase separation. For the control of the surface energy of the substrate, a silane deposition from the gas phase is utilized. The ordering behavior of a lamellar polystyrene-polymethylmethacrylate BCP with CFL is studied. In particular, the issues specific with phase separation in an imprint situation are addressed, the locally differing layer thickness and the fact that two surface energies contribute to the ordering process, the one of the substrate and the one of the stamp. Though further optimization is required to make use of CFL for efficient guiding, the first results reported here indicate the potential of this technique for stamp-induced guiding of BCPs. As it allows a multiple use of the stamp, such guiding is interesting and may replace the time- and cost-consuming pre-patterning of each substrate.

  20. The Food Stamp Program and Supplemental Security Income.

    2007-01-01

    The Food Stamp Program (FSP) and Supplemental Security Income (SSI) are important parts of national public assistance policy, and there is considerable overlap in the populations that the programs serve. About half of all SSI recipients reside in FSP recipient households. This article uses Social Security administrative data and the Food Stamp Quality Control samples for federal fiscal years 2001-2006 to study the prevalence of food stamp receipt among households with SSI recipients, the contribution of FSP to household income, and the importance of various FSP features in contributing to the well-being of recipient households. The prevalence of FSP participation among households that include SSI recipients is estimated to have grown steadily over the entire 2001-2006 period, rising from 47.4 percent in 2001 to 55.6 percent in 2006. This growth has occurred across all age groups of SSI recipients. The FSP contribution to household income has grown as well. In 2001, FSP increased the income of the households of SSI/FSP recipients by 13 percent; by 2006 the increase was 16.8 percent. Almost 80 percent of the food stamp recipient households that include SSI recipients receive increased benefits because of excess housing costs. In 2006, 44 percent of SSI recipients lived in households that did not receive food stamps. Given available information, it is difficult to gauge the FSP eligibility of nonparticipating households and, therefore, to assess the potential benefit of outreach efforts. Currently available measures of FSP take-up probably overstate participation among eligible households that include SSI recipients, and there is some evidence that enhanced state promotion of the FSP raises participation among households with SSI recipients. We conclude with recommendation for review and renewal of collaboration between the Food and Nutrition Service of the U.S. Department of Agriculture (the agency responsible for administering the FSP) and the Social Security Administration in ensuring that eligible SSI recipients utilize FSP benefits.

  5. Application of a dislocation based model for Interstitial Free (IF) steels to typical stamping simulations

    With a view to environmental, economic and safety concerns, car manufacturers need to design lighter and safer vehicles in ever shorter development times. In recent years, High Strength Steels (HSS) like Interstitial Free (IF) steels which have higher ratios of yield strength to elastic modulus, are increasingly used for sheet metal parts in automotive industry to meet the demands. Moreover, the application of sheet metal forming simulations has proven to be beneficial to reduce tool costs in the design stage and to optimize current processes. The Finite Element Method (FEM) is quite successful to simulate metal forming processes but accuracy largely depends on the quality of the material properties provided as input to the material model. Common phenomenological models roughly consist in the fitting of functions on experimental results and do not provide any predictive character for different metals from the same grade. Therefore, the use of accurate plasticity models based on physics would increase predictive capability, reduce parameter identification cost and allow for robust and time-effective finite element simulations. For this purpose, a 3D physically based model at large strain with dislocation density evolution approach was presented in IDDRG2009 by the authors [1]. This model allows the description of work-hardening's behavior for different loading paths (i.e. uni-axial tensile, simple shear and Bauschinger tests) taking into account several data from microstructure (i.e. grain size, texture, etc…). The originality of this model consists in the introduction of microstructure data in a classical phenomenological model in order to achieve work-hardening's predictive character for different metals from the same grade. Indeed, thanks to a microstructure parameter set for an Interstitial Free steel, it is possible to describe work-hardening behavior for different loading paths of other IF steels by only changing the mean grain size and the chemical composition. During sheet metal forming processes local material points may experience multi-axial and multi-path loadings. Before simulating actual industrial parts, automotive manufacturers use validation tools—e.g. the Cross-Die stamping test. Such typical stamping tests enable the evaluation of a complex distribution of strains. The work described is an implementation [2] of a 3D dislocation based model in ABAQUS/Explicit and its validation on a Finite Element (FE) Cross-Die model. In order to assess the performance and relevance of the 3D dislocation based model in the simulation of industrial forming applications, the results of thinning profiles predicted along several directions and the strain distribution were obtained and compared with experimental results for IF steels with grain sizes varying in the 8-22 ?m value range.

    Food Stamp Nutrition Education (FSNE) is an optional component of the Food Stamp Program aimed at improving food choices of program participants. The last decade has seen a dramatic expansion in FSNE, accompanied by increased interest in FSNE evaluation. The Society for Nutrition Education, as a leader in nutrition education research, has worked collaboratively with federal partners to improve FSNE evaluation. This is the first in a 3-part series of papers presented in this issue of the Journal of Nutrition Education and Behavior. The series reviews the issues, priority needs, and opportunities identified through this process; explains our current focus on the development of a brief measure assessing FSNE-relevant dietary behaviors; and describes plans for measurement development.

  9. Monitoring enzymatic degradation of pericellular matrices through SERS stamping

    We introduce a surface enhanced Raman spectroscopy (SERS) stamping approach for acquiring cell-surface specific vibrational spectra of individual living cells under physiological conditions. The SERS stamping approach utilizes a nanostructured metal surface on top of a lithographically defined piston that can be translated in 3-dimensions with nanometer resolution to contact living cells in solution with a pristine metal surface. We applied this approach to characterize the chemical composition of the cellular surface of living MCF7 breast cancer cells and to monitor its change upon addition of the enzyme hyaluronidase, which degrades major constituents of the pericellular matrix. Although the cell surface spectra show significant cell-to-cell fluctuations, a statistical barcode analysis of the spectra ensembles reveals systematic changes in the cell surface SERS spectra upon addition of hyaluronidase, which are consistent with a thinning of the pericellular matrix.We introduce a surface enhanced Raman spectroscopy (SERS) stamping approach for acquiring cell-surface specific vibrational spectra of individual living cells under physiological conditions.

    Consolidated thermites can be used as chemical heat sources. Pressing and sintering, a power metallurgy technique, has been developed to consolidate thermite parts with uniform density, composition, and calorific output. These materials are safe to handle, machineable, and generate minimum gas pressure upon reaction. This technique consists of die pressing various compositions of blended thermite powders, then isostatic pressing the parts before sintering to ensure the uniform density of the thermite composites. Parts sintered at various temperatures were examined metallographically for compositional uniformity and to determine whether diffusion between the powders had occurred. Flexure and tensile strength values were obtained to determine the temperature range required to produce strong parts. The coordination of metallography and strength values for various compositions and sintering temperature resulted in data that were used to optimize the fabrication process. Consolidation of thermite by pressing and sintering was found to be a valid process for producing uniform, dense, strong thermite parts.

  11. Investigation of Die Stress Profiles during Powder Compaction using Instrumented Die

    2008-06-01

    The radial stress profile in a cylindrical die during compaction of titanium (Ti) powder was investigated by experiments. The concept of an instrumented die was extended to design an enhanced instrumented die. Custom-made strain gage pins were used to measure the radial stress during powder compaction. The test fixture was designed to simulate double-action pressing. The measured die stress profile for Ti powder was compared with that for a commercially available iron (Fe) powder. The stress history shows that an appreciable residual stress remains in the die in the radial direction after the axial compaction stress is removed from the powder. Furthermore, the radial stress profile in the die, while under maximum axial compaction stress, is more uniform across the height of the Fe compact than that of the Ti compact. In addition, the residual stress profile in the die in the radial direction reduces symmetrically in both directions beyond the height of the compact for both powders. Finally, the Ti powder shows a significantly higher frictional coefficient at the maximum axial compaction stress, and consequently a higher maximum axial ejection stress than the Fe powder.

    Printing of versatile chemical and biological inks for protein and cell patterning was achieved using a simple and cost-effective flash foam stamp (FFS). The grey-scale mask fabricated stamp can generate multiple protein gradients with one-post stamping. Due to the importance of spatially controlled protein patterns in both biology and tissue engineering, this straightforward and reliable tool is an accessible solution for resource-limited laboratories conducting molecular patterning experiments.

    2011-06-21

    A heater for heating packaged die for burn-in and heat testing is described. The heater may be a ceramic-type heater with a metal filament. The heater may be incorporated into the integrated circuit package as an additional ceramic layer of the package, or may be an external heater placed in contact with the package to heat the die. Many different types of integrated circuit packages may be accommodated. The method provides increased energy efficiency for heating the die while reducing temperature stresses on testing equipment. The method allows the use of multiple heaters to heat die to different temperatures. Faulty die may be heated to weaken die attach material to facilitate removal of the die. The heater filament or a separate temperature thermistor located in the package may be used to accurately measure die temperature.

  18. Minerals on postage stamps: A mix of art, history, economics and geography

    NASA Astrophysics Data System (ADS)

    Glover, Paul

    2010-05-01

    Most people would agree that minerals represent some of the most beautiful natural objects known to mankind, especially in the form of precious and semi-precious gemstones. It is hardly surprising, therefore, that they are often illustrated on stamps. Examples are the fine crystalline forms represented as coloured etchings in the French 1986 issue, and the stylized simplicity of the mineral stamps that were part of the Swiss Pro Patria series, issued annually between 1958 and 1961. I aim in this presentation to introduce the beautiful world of mineral illustrations on stamps. The talk cannot be comprehensive because of the very large number of minerals and stamps concerned, but it will introduce the range of minerals depicted on stamps, then look in some greater detail at several sets from France, Southern Africa and East Germany. Minerals become the subject of sets of stamps for many reasons. In many cases, it is part of an attempt by the particular national post office to depict the whole of the natural history of their country in stamp form - a statement of nationality and politics. The 1986 French issue was an example which followed sets of stamps that had already portrayed insects, flowers, trees and birds native to France. We also find that certain countries have produced several sets of stamps to mark the importance to their economy of mining particular minerals. Many African states depend upon minerals for much of their wealth and economic power, explaining why, for instance, Sierra Leone issued over 35 stamps on the subject of diamonds between 1965 and 1978, and why over 77% of mineral stamps come from countries with major mining interests. Countries with traditional links with the history of the study of geology and mining also produce mineral stamps. These are usually European countries with a long record of the study of the Earth, such as Germany and Switzerland. Curiously enough, though, despite its fine tradition of geological observation and research, the United Kingdom has never produced a stamp depicting rocks or minerals. It is often said that the study of stamps is a study of history, language, culture, art, geography and politics. If this is true for stamps in general, it is particularly true for minerals on stamps.

    The six transmembrane protein of prostate 2 (STAMP2) is an androgen-regulated gene whose mRNA expression is increased in prostate cancer (PCa). Here, we show that STAMP2 protein expression is increased in human PCa compared with benign prostate that is also correlated with tumor grade and treatment response. We also show that STAMP2 significantly increased reactive oxygen species (ROS) in PCa cells through its iron reductase activity which also depleted NADPH levels. Knockdown of STAMP2 expression in PCa cells inhibited proliferation, colony formation, and anchorage-independent growth, and significantly increased apoptosis. Furthermore, STAMP2 effects were, at least in part, mediated by activating transcription factor 4 (ATF4), whose expression is regulated by ROS. Consistent with in vitro findings, silencing STAMP2 significantly inhibited PCa xenograft growth in mice. Finally, therapeutic silencing of STAMP2 by systemically administered nanoliposomal siRNA profoundly inhibited tumor growth in two established preclinical PCa models in mice. These data suggest that STAMP2 is required for PCa progression and thus may serve as a novel therapeutic target. PMID:25680860

  20. Formability Predictions in Stamping and Process Parameter Optimization Based on the Inverse Approach Code Fast_Stamp

    NASA Astrophysics Data System (ADS)

    Batoz, J. L.; Naceur, H.; Guo, Y. Q.

    2005-08-01

    A simplified (one step) method called "inverse approach" (IA) for the numerical analysis of the stamping process has been continuously developed by the authors since the end of the eighties. In the present paper we recall the main finite element formulation aspects, for an efficient estimation of the large elastoplastic strains encountered in deep drawing operations. The capabilities of the code Fast_Stamp include: fixed (imposed) initial blank, bending effects due to tool curvatures, blankholder restraining forces (including drawbeads). Considerations of bending and unbending during forming stages can improve the IA regarding stresses distribution. In this case satisfactory estimation of springback can result. Since 1996 we also developed "math based" optimization algorithms and strategies. The cost functions and constraints are mainly expressed to reduce or control the thickness changes, the localized necking, the wrinkling tendency, the springback after forming. The design variables are describing the shape of the blank, the additional (addendum) surfaces, the restraining forces due to drawbeads and the material properties such as anisotropy coefficient and hardening exponent. Optimization algorithms are mainly based on surface response techniques with moving least square approximation and SQP to find the optimum solution at each iteration. Selected results will be presented related to the design of additional surfaces.

    A method is disclosed for singulating die from a semiconductor substrate (e.g. a semiconductor-on-insulator substrate or a bulk silicon substrate) containing an oxide layer (e.g. silicon dioxide or a silicate glass) and one or more semiconductor layers (e.g. monocrystalline or polycrystalline silicon) located above the oxide layer. The method etches trenches through the substrate and through each semiconductor layer about the die being singulated, with the trenches being offset from each other around at least a part of the die so that the oxide layer between the trenches holds the substrate and die together. The trenches can be anisotropically etched using a Deep Reactive Ion Etching (DRIE) process. After the trenches are etched, the oxide layer between the trenches can be etched away with an HF etchant to singulate the die. A release fixture can be located near one side of the substrate to receive the singulated die.

    Over 25 years ago, Kubler-Ross identified anger as a predictable part of the dying process. When the dying patient becomes angry in the clinical setting, all types of communication become strained. Physicians can help the angry dying patient through this difficult time by using 10 rules of engagement. When physicians engage and empathize with these patients, they improve the patient's response to pain and they reduce patient suffering. When physicians educate patients on their normal responses to dying and enlist them in the process of family reconciliation, they can impact the end-of-life experience in a positive way.

    1981-01-01

    Three experimental research designs investigating candidate materials and processes involved in protective die surface coating procedures by sputter deposition, using ion beam technologies, are discussed. Various pre-test results show that none of the coatings remained completely intact for 15,000 test cycles. The longest lifetime was observed for coatings such as tungsten, platinum, and molybdenum which reduced thermal fatigue, but exhibited oxidation and suppressed crack initiation only as long as the coating did not fracture. Final test results confirmed earlier findings and coatings with Pt and W proved to be the candidate materials to be used on a die surface to increase die life. In the W-coated specimens, which remained intact on the surface after thermal fatigue testing, no oxidation was found under the coating, although a few cracks formed on the surface where the coating broke down. Further research is planned.

    Staehle, Robert L.; Terrile, Richard J.; Weinstein, Stacy S.

    1994-01-01

    In this time of constrained budgets, the primary question facing planetary explorers is not 'Can we do it?' but 'Can we do it cheaply?' Taunted by words on a postage stamp, a group of mission designers at the Jet Propulsion Laboratory is struggling to find a cheap way to go to Pluto. Three primary goals were set by the science community: (1) imaging of Pluto and Charon, (2) mapping their surface composition, and (3) characterizing Pluto's atmosphere. The spacecraft will be designed around these primary goals. With the help of the Advanced Technology Insertion (ATI) process $5 million was alloted for two years to shop for lightweight components and subsystems using new technology never tried on a planetary mission. The process for this search and development is described.

    2002-01-01

    An attachment structure is disclosed for attaching a die to a supporting substrate without the use of adhesives or solder. The attachment structure, which can be formed by micromachining, functions purely mechanically in utilizing a plurality of shaped pillars (e.g. round, square or polygonal and solid, hollow or slotted) that are formed on one of the die or supporting substrate and which can be urged into contact with various types of mating structures including other pillars, a deformable layer or a plurality of receptacles that are formed on the other of the die or supporting substrate, thereby forming a friction bond that holds the die to the supporting substrate. The attachment structure can further include an alignment structure for precise positioning of the die and supporting substrate to facilitate mounting the die to the supporting substrate. The attachment structure has applications for mounting semiconductor die containing a microelectromechanical (MEM) device, a microsensor or an integrated circuit (IC), and can be used to form a multichip module. The attachment structure is particularly useful for mounting die containing released MEM devices since these devices are fragile and can otherwise be damaged or degraded by adhesive or solder mounting.

  15. Conical tungsten stamps for the replication of pore arrays in anodic aluminium oxide films.

    PubMed

    LeClere, D J; Thompson, G E; Derby, B

    2009-06-17

    A tungsten master stamp has been generated by applying a novel procedure that includes two-step anodizing, followed by sequential anodizing and pore widening to develop nominally funnelled pores. These conical-shaped pores were filled with tungsten by sputter coating to manufacture a master stamp. Under a pressure of 65 MPa, the master stamp successfully embossed the surface of annealed and electropolished aluminium. The embossed surface was then used to control the position of pores created by anodizing under the conditions used to produce the original pore array. PMID:19468168

    This level sets the stage for the design philosophy called “Triadic Game Design” (TGD). This design philosophy can be summarized with the following sentence: it takes two to tango, but it takes three to design a meaningful game or a game with a purpose. Before the philosophy is further explained, this level will first delve into what is meant by a meaningful game or a game with a purpose. Many terms and definitions have seen the light and in this book I will specifically orient at digital games that aim to have an effect beyond the context of the game itself. Subsequently, a historical overview is given of the usage of games with a serious purpose which starts from the moment we human beings started to walk on our feet till our contemporary society. It turns out that we have been using games for all kinds of non-entertainment purposes for already quite a long time. With this introductory material in the back of our minds, I will explain the concept of TGD by means of a puzzle. After that, the protagonist of this book, the game Levee Patroller, is introduced. Based on the development of this game, the idea of TGD, which stresses to balance three different worlds, the worlds of Reality, Meaning, and Play, came into being. Interested? Then I suggest to quickly “press start!”

  1. Evaluation of Draw Beads Influence on Intricate Shape Stamping Drawing Process

    2014-12-01

    Paper concerns evaluation of influence of shape, size and location of rectangular and semicircular draw beads on sheet-metal forming process. For analysis the simulations of forming process of selected two types of intricate shape stampings with similar ground plan and with approximately the same height from steel strip DC04 with the use of models of optimal blanks made by BSE (Blank Size Engineering) modul of simulation program Dynaform 5.7 were carried out. From simulations of forming process in simulation program Dynaform 5.7 followed that the most suitable is drawing without use of draw beads because cracks in stamping bottom corners do not arise. In the case of undesirable secondary waviness in the walls of intricate shape stamping the drawing with draw beads could be used but it would be necessary to increase the radius at the bottom of both stampings alternatively to choose another material with higher formability.

    Liquid-metal-induced embrittlement (LMIE) of galvanized hot stamping steel occurs due to the simultaneous application of stress and the presence of a liquid Zn surface layer during the hot stamping process. The mechanism specific to the liquid metal induced embrittlement occurring during hot stamping was investigated in detail. It was found that when a tensile stress was applied, liquid Zn could penetrate along grain boundaries in the steel matrix at temperatures above the Liquid + ?-Fe (Zn) ? ?1 peritectic transformation temperature of 1055 K (782 °C). The results show that an increase of the annealing time prior to hot stamping is an effective way to prevent LMIE by the elimination of the liquid phase.

    We propose and experimentally demonstrate a new method called SF-STAMP for sequentially timed all-optical mapping photography (STAMP) that utilizes spectral filtering. SF-STAMP is composed of a diffractive optical element (DOE), a band-pass filter, and two Fourier transform lenses. Using a linearly frequency-chirped pulse and converting the wavelength to the time axis, we realize single-shot ultrafast burst imaging. As an experimental demonstration of SF-STAMP, we monitor the dynamics of a laser ablation using a linearly frequency-chirped broadband pulse (>100 nm) that is temporally stretched up to ~40 ps. This imaging method is expected to be effective for investigating ultrafast dynamics in a diverse range of fields, such as photochemistry, plasma physics, and fluidics. PMID:26698529

    This communication describes a simple method that uses a thin film of octafluorocyclobutane (OFCB) polymer for efficient nanoscale transfer printing (nTP). Plasma polymerization of OFCB produces a Teflon-like fluoropolymer which strongly adheres and conformally covers 3-D inorganic stamp. The inherently low surface energy of in-situ deposited OFCB polymer on nanoscale silicon features is demonstrated as a unique nanocomposite stamp to fabricate various test structures with improved nTP feature resolution down to sub 100 nm.

    Baker, Robert R. (Livonia, MI); Hartsock, Dale L. (Livonia, MI)

    1982-01-01

    This disclosure relates to an improved method for achieving the best bond strength and for minimizing distortion and cracking of hot pressed articles. In particular, in a method for hot press forming both an outer facing circumferential surface of and an inner portion of a hub, and of bonding that so-formed outer facing circumferential surface to an inner facing circumferential surface of a pre-formed ring thereby to form an article, the following improvement is made. Normally, in this method, the outside ring is restrained by a restraining sleeve of ring-shaped cross-section having an inside diameter. A die member, used to hot press form the hub, is so-formed as to have an outside diameter sized to engage the inside diameter of the restraining sleeve in a manner permitting relative movement therebetween. The improved method is one in which several pairs of matched restraining sleeve and die member are formed with each matched pair having a predetermined diameter. The predetermined diameter of each matched pair is different from another matched pair by stepped increments. The largest inside diameter of a restraining sleeve is equal to the diameter of the outer facing circumferential surface of the hub. Each pair of the matched restraining sleeve and die member is used to form an article in which an inside hub is bonded to an outside ring. The several samples so-formed are evaluated to determine which sample has the best bond formed between the hub and the ring with the least or no cracking or distortion in the ring portion of the article. Thereafter, the matched restraining sleeve and die member which form the article having the best bonding characteristics and least distortion cracking is then used for repeated formations of articles.

    2009-09-08

    The present invention is generally directed to catalyzed hot stamp methods for polishing and/or patterning carbon nanotube-containing substrates. In some embodiments, the substrate, as a carbon nanotube fiber end, is brought into contact with a hot stamp (typically at 200-800.degree. C.), and is kept in contact with the hot stamp until the morphology/patterns on the hot stamp have been transferred to the substrate. In some embodiments, the hot stamp is made of material comprising one or more transition metals (Fe, Ni, Co, Pt, Ag, Au, etc.), which can catalyze the etching reaction of carbon with H.sub.2, CO.sub.2, H.sub.2O, and/or O.sub.2. Such methods can (1) polish the carbon nanotube-containing substrate with a microscopically smooth finish, and/or (2) transfer pre-defined patterns from the hot stamp to the substrate. Such polished or patterned carbon nanotube substrates can find application as carbon nanotube electrodes, field emitters, and field emitter arrays for displays and electron sources.

  19. A Fully Automated and Robust Method to Incorporate Stamping Data in Crash, NVH and Durability Analysis

    2011-08-01

    Crash, NVH (Noise, Vibration, Harshness), and durability analysis are commonly deployed in structural CAE analysis for mechanical design of components especially in the automotive industry. Components manufactured by stamping constitute a major portion of the automotive structure. In CAE analysis they are modeled at a nominal state with uniform thickness and no residual stresses and strains. However, in reality the stamped components have non-uniformly distributed thickness and residual stresses and strains resulting from stamping. It is essential to consider the stamping information in CAE analysis to accurately model the behavior of the sheet metal structures under different loading conditions. Especially with the current emphasis on weight reduction by replacing conventional steels with aluminum and advanced high strength steels it is imperative to avoid over design. Considering this growing need in industry, a highly automated and robust method has been integrated within Altair Hyperworks® to initialize sheet metal components in CAE models with stamping data. This paper demonstrates this new feature and the influence of stamping data for a full car frontal crash analysis.

  20. Insulation from basaltic stamp sand. Final technical report

    SciTech Connect

    Williams, F. D.

    1981-04-01

    A Midwest Appropriate Technology Grant was awarded to determine the technical and economic feasibility of producing mineral-fiber insulation directly from extensive deposits of basaltic sand produced during former mining and milling operations in the Keweenaw Peninsula region of Michigan's Upper Peninsula. The amounts of local basaltic sands available and representative chemical compositions were determined. The variation of viscosity with temperature and chemical composition was estimated. Samples were melted and either pulled or blown into fiber. In all cases fiber could be made with a reasonable tensile strength to ensure usefulness. It was concluded that it was technically feasible to produce fibers from basaltic stamp sands of the Upper Peninsula of Michigan. A technical feasibility study using published data, a cost and design analysis of a basalt fiber production plant, a market survey of fiber needs, and an economic analysis for investing in a basalt fiber venture was undertaken. These studies concluded that the local production of basaltic insulation was both feasible and economically reasonable. It was suggested that the plant be located in a region of greater population density with lower utility costs. A representative one-third of these studies is included as appendices A, B, C, and D.

    Objectives To evaluate erectile function following high dose radiotherapy for prostate cancer using the international index of erectile function (IIEF), expanded prostate cancer index composite (EPIC), and stamp test. Methods Men with favorable and intermediate risk prostate cancer were assigned to receive prostate intensity modulated radiotherapy (IMRT) vs. an erectile tissue-sparing IMRT technique on a phase III randomized prospective study. The stamp test, IIEF, and EPIC questionnaires were completed at baseline, 6 months, one year, and two years after IMRT. Sexual Health Inventory for Men (SHIM) scores were abstracted from IIEF questionnaires. A partner questionnaire, designated IIEF-P, modeled after the IIEF but from the perspective of the partner, was collected. Results Ninety four men enrolled on the trial who completed at least one questionnaire or one stamp test were analyzed. The median age of the patient population was 62.5 years. The median RT dose was 76 Gy (range: 74–80 Gy). At 6-months and one year after high-dose IMRT, a positive stamp result significantly correlated with median EPIC sexual summary, sexual function (EF), and bother subscale scores. Additionally, 6-months after IMRT the stamp test correlated with median IIEF, IIEF EF domain, and SHIM scores. Robust concordance for the IIEF and SHIM results was appreciated between responding patients: partner pairs. Conclusions Nocturnal tumescence indicated by a positive stamp test correlates well with established quality of life questionnaires after IMRT. The stamp test should strongly be considered as an objective measure of erectile function in future studies of ED in prostate cancer patients. PMID:22749428

  6. Die kalte Zunge

    Bartels, Sören; Müller, Rüdiger

    Gefühlte Temperaturen. Ist ein Null Grad Celsius kalter Metallstab eigentlich kälter als ein Holzstab mit der selben Temperatur? Rein physikalisch gesehen natürlich nicht, aber wenn wir beide Stäbe anfassen, kommt uns der Metallstab deutlich kälter vor. Und wer kennt nicht die Szene aus dem Film Dumm und Dümmer in der Harry mit seiner Zunge am Metallrahmen des Skilifts hängen bleibt.Würde das auch passieren, wenn man an einem eiskalten Stück Holz lecken würde? Wohl kaum, doch woran liegt das eigentlich? Unterschiedliche Materialien haben verschiedene Fähigkeiten, Wärme zu übertragen und zu leiten. So transportiert Metall die von der Zunge ausgehende Wärme sehr schnell weiter und verändert seine Temperatur kaum, während die Zunge abkühlt. Holz hingegen leitet Wärme fast gar nicht und daher wird der Teil, der von der Zunge berührt wird, aufgewärmt.

  7. Optimum pinch grips in the handling of dies.

    PubMed

    Heffernan, C; Freivalds, A

    2000-08-01

    Handling roller-press dies has caused numerous work-related musculoskeletal disorders in the leather industry. The dies are quite large (0.61 x 0.30 m), heavy (3.5 kg) and are difficult to handle because of the large pinch span requirements (up to 16 cm). The purpose of this study was to determine the optimum pinch span and optimum crossbar angulation to minimize die handling forces. Five-finger pulp-pinch forces were measured on five males and five females with a force-sensitive-resistor instrumented glove while handling a simulated adjustable die. Maximum pinch forces occurred at pinch spans between 1.27 and 3.81 cm, with average female strengths being 57% of average male pinch strengths. Minimum pinch forces to hold the die occurred at a 45 degrees angulation and increased linearly as the angle approached 90 degrees or the normal vertical orientation. The simplest solution to redesigning the dies is to: (1) decrease the distance between the braces to less than 4 cm and (2) slant the braces at 45 degrees. PMID:10975667

  8. Zinc coated sheet steel for press hardening

    NASA Astrophysics Data System (ADS)

    Ghanbari, Zahra N.

    Galvanized steels are of interest to enhance corrosion resistance of press-hardened steels, but concerns related to liquid metal embrittlement have been raised. The objective of this study was to assess the soak time and temperature conditions relevant to the hot-stamping process during which Zn penetration did or did not occur in galvanized 22MnB5 press-hardening steel. A GleebleRTM 3500 was used to heat treat samples using hold times and temperatures similar to those used in industrial hot-stamping. Deformation at both elevated temperature and room temperature were conducted to assess the coating and substrate behavior related to forming (at high temperature) and service (at room temperature). The extent of alloying between the coating and substrate was assessed on undeformed samples heat treated under similar conditions to the deformed samples. The coating transitioned from an ? + Gamma1 composition to an ? (bcc Fe-Zn) phase with increased soak time. This transition likely corresponded to a decrease in availability of Zn-rich liquid in the coating during elevated temperature deformation. Penetration of Zn into the substrate sheet in the undeformed condition was not observed for any of the processing conditions examined. The number and depth of cracks in the coating and substrate steel was also measured in the hot-ductility samples. The number of cracks appeared to increase, while the depth of cracks appeared to decrease, with increasing soak time and increasing soak temperature. The crack depth appeared to be minimized in the sample soaked at the highest soak temperature (900 °C) for intermediate and extended soak times (300 s or 600 s). Zn penetration into the substrate steel was observed in the hot-ductility samples soaked at each hold temperature for the shortest soak time (10 s) before being deformed at elevated temperature. Reduction of area and elongation measurements showed that the coated sample soaked at the highest temperature and longest soak time maintained the highest ductility when compared to the uncoated sample processed under the sample conditions. Fractography of the hot-ductility samples showed features associated with increased ductility with increased soak time for all soak temperatures. Heat treatments (without elevated temperature deformation) and subsequent room temperature deformation were conducted to investigate the "in-service" behavior of 22MnB5. The uncoated and coated specimens deformed at room temperature showed similar ultimate tensile strength and ductility values. The only notable differences in the room temperature mechanical behavior of uncoated and coated samples processed under the same conditions were a result of differences in the substrate microstructure. All samples appeared to have ductile fracture features; features characteristic of liquid metal embrittlement were not observed.

  9. Luman is involved in osteoclastogenesis through the regulation of DC-STAMP expression, stability and localization.

    Luman (also known as CREB3) is a type-II transmembrane transcription factor belonging to the OASIS family that localizes to the endoplasmic reticulum (ER) membrane under normal conditions. In response to ER stress, OASIS-family members are subjected to regulated intramembrane proteolysis (RIP), following which the cleaved N-terminal fragments translocate to the nucleus. In this study, we show that treatment of bone marrow macrophages (BMMs) with cytokines - macrophage colony-stimulating factor (M-CSF) and RANKL (also known as TNFSF11) - causes a time-dependent increase in Luman expression, and that Luman undergoes RIP and becomes activated during osteoclast differentiation. Small hairpin (sh)RNA-mediated knockdown of Luman in BMMs prevented the formation of multinucleated osteoclasts, concomitant with the suppression of DC-STAMP, a protein that is essential for cell-cell fusion in osteoclastogenesis. The N-terminus of Luman facilitates promoter activity of DC-STAMP, resulting in upregulation of DC-STAMP expression. Furthermore, Luman interacts with DC-STAMP, and controls its stability and localization. These results suggest that Luman regulates the multinucleation of osteoclasts by promoting cell fusion of mononuclear osteoclasts through DC-STAMP induction and intracellular distribution during osteoclastogenesis.

    2015-03-01

    Time travel through 150 years of Italian postage stamp issues has allowed defining the evolution of the recurring pigments in stamp designs by means of Raman and FTIR spectroscopy. Numerous exemplars have been analyzed, covering the entire production of stamps for both the Italian Kingdom and Republic. Raman and FTIR spectra showed the changeover from Prussian blue to copper phthalocyanine inks in 1958. The entire succession for red inks was also recognized to develop from the original cinnabar to red ochre and minium and finally to red azo pigments. The changes in orange printing ink proceeded on a similar path. The first orange Italian exemplar was printed employing a mixture of chrome orange and red ochre. In 1929 this combination was replaced by azo pigments. Green stamps belonging to the first issues entailed the choice of blue and orange inks, namely chrome orange and Prussian blue. Later on, an ink composed mainly of phthalocyanine was employed as the green dye. The merging of data coming from Raman microscopy and FTIR-ATR spectroscopy, both non-destructive techniques, has allowed the characterization of stamp designs and potentially provides direct and fast evidence for the recognition of forged exemplars.

  11. Who receives food stamps during adulthood? Analyzing repeatable events with incomplete event histories.

    Grieger, Lloyd D; Danziger, Sheldon H

    2011-11-01

    Using data from the Panel Study of Income Dynamics (PSID) from 1968 to 2005, we estimate the cumulative probability that young adults in the United States will receive food stamps during adulthood, and examine how that probability varies with an individual's income and education at age 25 as well as by race and gender. We find that the probability of first food stamp receipt as an adult declines sharply with age, indicating that most adult recipients do so by age 40. Also, those receiving food stamps in early adulthood are likely to receive them again. For these reasons, and because food stamp receipt is a repeatable event, life table analyses that include individuals who are not observed until after they become exposed to the risk of food stamp receipt (whom we label "late entrants") are likely to overstate cumulative participation during adulthood. For example, one often-cited study included individuals who enter their sample after age 20 (late entrants) and report that 50.8% of 20-year-olds are recipients by age 65. In contrast, when we exclude late entrants, we find that 39.2% of 20-year-olds and 29.7% of 25-year-olds receive benefits during adulthood. PMID:21853399

  12. Should Canadian health promoters support a food stamp-style program to address food insecurity?

    PubMed

    Power, Elaine M; Little, Margaret H; Collins, Patricia A

    2015-03-01

    Food insecurity is an urgent public health problem in Canada, affecting 4 million Canadians in 2012, including 1.15 million children, and associated with significant health concerns. With little political will to address this significant policy issue, it has been suggested that perhaps it is time for Canada to try a food stamp-style program. Such a program could reduce rates of food insecurity and improve the nutritional health of low-income Canadians. In this article, we explore the history of the US food stamp program; the key impetus of which was to support farmers and agricultural interests, not to look after the needs of people living in poverty. Though the US program has moved away from its roots, its history has had a lasting legacy, cementing an understanding of the problem as one of lack of food, not lack of income. While the contemporary food stamp program, now called Supplemental Nutrition Assistance Program (SNAP), reduces rates of poverty and food insecurity, food insecurity rates in the USA are significantly higher than those in Canada, suggesting a food stamp-style program per se will not eliminate the problem of food insecurity. Moreover, a food stamp-style program is inherently paternalistic and would create harm by reducing the autonomy of participants and generating stigma, which in itself has adverse health effects. Consequently, it is ethically problematic for health promoters to advocate for such a program, even if it could improve diet quality. PMID:25256001

    2013-12-01

    The hot stamping of boron steels is widely used to produce ultra high strength automobile components without any spring back. The ultra high strength of final products is attributed to the fully martensitic microstructure that is obtained through the simultaneous forming and quenching of the hot blanks after austenization. In the present study, a mathematical model incorporating both heat transfer and the transformation of austenite is presented. A FORTRAN program based on finite element technique has been developed which permits the temperature distribution and microstructure evolution of high strength steel during hot stamping process. Two empirical diffusion-dependent transformation models under isothermal conditions were employed respectively, and the prediction capability on mechanical properties of the models were compared with the hot stamping experiment of an automobile B-pillar part.

    Seventeen out of 21 obliterated stamped serial numbers on test specimens of copper, brass, steel, and aluminum were successfully restored. Cavitation induced in water by a piezoelectric transducer was the mechanism used. Primarily, smeared metal was removed from the number grooves by the force of the cavitation, however, numbers were also restored at depths at or below the level of the stamped grooves. The feasibility of this technique as a low cost tool for crime laboratories has been clearly demonstrated. The technique is applicable to a variety of materials, and no previous surface or chemical treatments are necessary.

    2015-05-01

    We describe a process for the fabrication of a Ni stamp that is applied to the microstructuring of polymers by hot embossing. The target devices are microcontainers that have a potential application in oral drug delivery. Each container is a 3D, cylindrical, high aspect ratio microstructure obtained by defining a reservoir and a separating trench with different depths of 85 and 125?µm, respectively, in a single embossing step. The fabrication of the required two leveled stamp is done using a modified DEEMO (dry etching, electroplating and molding) process. Dry etching using the Bosch process and electroplating are optimized to obtain a stamp with smooth stamp surfaces and a positive sidewall profile.

    This invention teaches a method of cutting a narrow slot in an extrusion die with an electrical discharge machine by first drilling spaced holes at the ends of where the slot will be, whereby the oil can flow through the holes and slot to flush the material eroded away as the slot is being cut. The invention further teaches a method of extruding a very thin ribbon of solid highly reactive material such as lithium or sodium through the die in an inert atmosphere of nitrogen, argon, or the like as in a glovebox. The invention further teaches a method of stamping out sample discs from the ribbon and of packaging each disc by sandwiching it between two aluminum sheets and cold welding the sheets together along an annular seam beyond the outer periphery of the disc. This provides a sample of high purity reactive material that can have a long shelf life.

  8. Die drool and polymer degradation

    NASA Astrophysics Data System (ADS)

    Hoy, Geoffrey Stephen; Giacomin, Alan Jeffrey; Gilbert, Peter Hunter

    2015-04-01

    Die drool is an operational problem associated with polymer extrusion. Extrudate collects outside of the die, necessitating periodic disruptions for cleaning. There exists some debate as to the mechanism that produces die drool: stress induced fractionation or thermal degradation. This paper examines the latter. In cohesive failure, a slip discontinuity develops in the velocity profile, where heat is generated by friction. This slip heating can contribute to resin degradation, resulting in lower molecular weight fragments in the die drool. This paper examines the kinetics of this degradation, its influence on die drool rates, and on the resulting polymer concentration profiles in the drool layer and in the bulk.

    2014-11-01

    Based on the frame work of continuum damage mechanics, a research work of anisotropic damage evolution in warm stamping process of magnesium alloy sheets has been carried out by means of a combined experimental-numerical method. The aim was to predict formability of warm stamping of AZ31 Mg alloy sheets by taking the thermal and damage effects into account. In the presented work, a temperature-dependent anisotropic yield function suitable for cold rolling sheet metals together with an anisotropic damage model was implemented into the a VUMAT subroutine for ABAQUS/EXPLICIT. The evolution of internal damage in the form of void growth and coalescence in AZ31 Mg alloy sheet was observed by means of scanning electron microscopy (SEM). Moreover, a coupled thermo-mechanical simulation of the stamping process was performed using the implemented code at different temperatures. The parameters employed in the simulation were determined by the standard tensile tests and algebraic manipulation. The overall anisotropic damage process from crack initiation to final propagation in local area of blank was simulated. Numerical results show that the prediction of the site of crack initiation and the orientation of crack propagation are consistent with the data observed in warm stamping experiments.

  4. Strawberry notch homologue 2 regulates osteoclast fusion by enhancing the expression of DC-STAMP.

    Osteoclasts are multinucleated cells formed by fusion of mononuclear precursors in response to receptor activator of nuclear factor ?B (NF-?B) ligand (RANKL). We found that RANKL induced expression of the DExD/H helicase family corepressor strawberry notch homologue 2 (Sbno2). Previous in vitro studies showed that Sbno2 is induced by IL-10 and is involved in NF-?B repression. However, the role of Sbno2 in vivo and its pleiotropic functions are unknown. Sbno2 gene targeting resulted in normal NF-?B activation by TLR ligands. However, Sbno2-deficient mice exhibited increased bone mass due to impaired osteoclast fusion. Expression of dendritic cell-specific transmembrane protein (DC-STAMP), a critical player in osteoclast fusion, was significantly attenuated, and cell fusion of Sbno2-deficient osteoclasts was rescued by DC-STAMP. Sbno2 directly bound to T cell acute lymphocytic leukemia 1 (Tal1) and attenuated its inhibition of DC-STAMP expression, leading to activation of the DC-STAMP promoter by microphthalmia-associated transcription factor (MITF). Thus, Sbno2 plays a pivotal role in bone homeostasis in vivo by fine-tuning osteoclast fusion. PMID:23980096

  7. Determination of Proper Austenitization Temperatures for Hot Stamping of AISI 4140 Steel

    NASA Astrophysics Data System (ADS)

    2014-04-01

    High strength steels are desirable materials for use in automobile bodies in order to reduce vehicle weight and increase the safety of car passengers, but steel grades with high strength commonly show poor formability. Recently, steels with controlled microstructures and compositions are used to gain adequate strength after hot stamping while maintaining good formability during processing. In this study, microstructure evolutions and changes in mechanical properties of AISI 4140 steel sheets resulting from the hot stamping process at different austenitization temperatures were investigated. To determine the proper austenitization temperatures, the results were compared with those of the cold-worked and cold-worked plus quench-tempered specimens. Comparisons showed that the austenitization temperatures of 1000 and 1100 °C are proper for hot stamping of 3-mm-thick AISI 4140 steel sheets due to the resultant martensitic microstructure which led to the yield and ultimate tensile strength of 1.3 and 2.1 GPa, respectively. Such conditions resulted in more favorable simultaneous strength and elongation than those of hot-stamped conventional boron steels.

  8. Time-stamping system for nuclear physics experiments at RIKEN RIBF

    A time-stamping system for nuclear physics experiments has been introduced at the RIKEN Radioactive Isotope Beam Factory. Individual trigger signals can be applied for separate data acquisition (DAQ) systems. After the measurements are complete, separately taken data are merged based on the time-stamp information. In a typical experiment, coincidence trigger signals are formed from multiple detectors to take desired events only. The time-stamping system allows the use of minimum bias triggers. Since coincidence conditions are given by software, a variety of physics events can be flexibly identified. The live time for a DAQ system is important when attempting to determine reaction cross-sections. However, the combined live time for separate DAQ systems is not clearly known because it depends not only on the DAQ dead time but also on the coincidence conditions. Using the proposed time-stamping system, all trigger timings can be acquired, so that the combined live time can be easily determined. The combined live time is also estimated using Monte Carlo simulations, and the results are compared with the directly measured values in order to assess the accuracy of the simulation.

  18. Analysis and modeling of hot extrusion die for its service life enhancement

    NASA Astrophysics Data System (ADS)

    Akhtar, Syed Sohail

    Aluminum extrusion finds extensive application in the construction, automobile and aerospace industries. High pressures, elevated temperatures, complex and intricate section geometries lead to repeated mechanical and thermal stresses in the die and affiliated tooling. Product rework and rejects can be traced back to various defects spread over the die life cycle: die design, die manufacture and heat treatment, process parameters, inprocess die maintenance/correction and, billet type and quality. Therefore, improved and efficient service life of die and related tooling used in the extrusion press is one the most important factors in maximizing productivity and minimizing cost for ensuring the economical efficiency of an aluminum extrusion plant. How often a die has to be scrapped and replaced with a new one directly contributes to the commercial viability of producing a certain profile. The focus of the current work is on three distinct yet inter-related studies pertaining to the improvement of aluminum extrusion die. Study-A (Die Failure Analysis) is an investigation of various modes and critical failure types based on industrial data (Chapter-2 ), examination of failed dies and finite element simulation for identification of critical process parameters and design features in die fatigue-life (Chapter-3). In Study-B (Die Surface Hardening Treatment), two-stage controlled gas nitriding process for H13 steel is evaluated, both experimentally and numerically, in terms of nitrided case morphology and properties (Chapter-4) followed by experimental and numerical investigation of the effects of repeated nitriding (Chapter-5), pre-nitriding surface preparation (Chapter-6) and die profile geometry (Chapter-7) on nitriding performance in regard to die service life. In Study-C (Effect of Billet Quality on Die Life), the effect of billet quality and related influencing extrusion parameters on the die service life is investigated based on industrial data and some regression-based die life models are proposed (Chapter-8 ). This is followed by a detailed microstructural investigation of different billet samples and finite element analysis of extrusion process to observe the influence of smelter (primary) and recycled (secondary) billets on the useful life of extrusion die (Chapter-9).

    2016-03-01

    The potential of FT-NIR and FT-Raman spectroscopies to characterise the gum applied on the backside of ancient stamps was investigated for the first time. This represents a very critical issue for the collectors' market, since gum conditions heavily influence stamp quotations, and fraudulent application of synthetic gum onto damaged stamp backsides to increase their desirability is a well-documented practice. Spectral data were processed by exploratory pattern recognition tools. In particular, application of principal component analysis (PCA) revealed that both of the spectroscopic techniques provide information useful to characterise stamp gum. Examination of PCA loadings and their chemical interpretation confirmed the robustness of the outcomes. Fusion of FT-NIR and FT-Raman spectral data was performed, following both a low-level and a mid-level procedure. The results were critically compared with those obtained separately for the two spectroscopic techniques. PMID:26717838

    Nutrition risk, nutrient intake, and selected socioeconomic characteristics of elderly food stamp recipients were compared with elderly people who were eligible for food stamps but did not participate in the program. Data were collected by survey using a convenience sample of 200 low-income elderly people living in subsidized housing. Although there were no significant differences in food group or nutrient intake between participants and nonparticipants, overall, these low-income subjects did not meet minimum Dietary Reference Intake (DRI) standards for many nutrients and had caloric and food group serving intakes that were below recommendations. Food Stamp Program participants were at significantly higher nutrition risk than their nonparticipating peers as detected by the Nutrition Screening Initiative Checklist (P< or =.01) and other indicators of disability. It seems that those already at highest risk were in fact participating in the Food Stamp Program because those eligible but not participating had significantly higher incomes and were at significantly lower nutritional risk.

  10. Two Piece Compaction Die Design

    SciTech Connect

    Coffey, Ethan N

    2010-03-01

    Compaction dies used to create europium oxide and tantalum control plates were modeled using ANSYS 11.0. Two-piece designs were considered in order to make the dies easier to assemble than the five-piece dies that were previously used. The two areas of concern were the stresses at the interior corner of the die cavity and the distortion of the cavity wall due to the interference fit between the two pieces and the pressure exerted on the die during the compaction process. A successful die design would have stresses less than the yield stress of the material and a maximum wall distortion on the order of 0.0001 in. Design factors that were investigated include the inner corner radius, the value of the interference fit, the compaction force, the size of the cavity, and the outer radius and geometry of the outer ring. The results show that for the europium oxide die, a 0.01 in. diameter wire can be used to create the cavity, leading to a 0.0055 in. radius corner, if the radial interference fit is 0.003 in. For the tantalum die, the same wire can be used with a radial interference fit of 0.001 in. Also, for the europium oxide die with a 0.003 in. interference fit, it is possible to use a wire with a diameter of 0.006 in. for the wire burning process. Adding a 10% safety factor to the compaction force tends to lead to conservative estimates of the stresses but not for the wall distortion. However, when the 10% safety factor is removed, the wall distortion is not affected enough to discard the design. Finally, regarding the europium oxide die, when the cavity walls are increased by 0.002 in. per side or the outer ring is made to the same geometry as the tantalum die, all the stresses and wall distortions are within the desired range. Thus, the recommendation is to use a 0.006 in. diameter wire and a 0.003 in. interference fit for the europium oxide die and a 0.01 in. diameter wire and a 0.001 in. interference fit for the tantalum die. The dies can also be made to have the same outer geometry if desired.

  11. Time Stamp Attack on Wide Area Monitoring System in Smart Grid

    Zhang, Zhenghao; Li, Husheng; Pei, Changxing

    2011-01-01

    Security becomes an extremely important issue in smart grid. To maintain the steady operation for smart power grid, massive measurement devices must be allocated widely among the power grid. Previous studies are focused on false data injection attack to the smart grid system. In practice, false data injection attack is not easy to implement, since it is not easy to hack the power grid data communication system. In this paper, we demonstrate that a novel time stamp attack is a practical and dangerous attack scheme for smart grid. Since most of measurement devices are equipped with global positioning system (GPS) to provide the time information of measurements, it is highly probable to attack the measurement system by spoofing the GPS. By employing the real measurement data in North American Power Grid, simulation results demonstrate the effectiveness of the time stamp attack on smart grid.

    We report stamping surface-enhanced Raman spectroscopy (S-SERS) for label-free, multiplexed, molecular sensing and large-area, high-resolution molecular imaging on a flexible, nonplasmonic surface without solution-phase molecule transfer. In this technique, a polydimethylsiloxane (PDMS) thin film and nanoporous gold disk SERS substrate play the roles as molecule carrier and Raman signal enhancer, respectively. After stamping the SERS substrate onto the PDMS film, SERS measurements can be directly taken from the "sandwiched" target molecules. The performance of S-SERS is evaluated by the detection of Rhodamine 6G, urea, and its mixture with acetaminophen, in a physiologically relevant concentration range, along with the corresponding SERS spectroscopic maps. S-SERS features simple sample preparation, low cost, and high reproducibility, which could lead to SERS-based sensing and imaging for point-of-care and forensics applications.

  17. Novel Method for Predicting Hardness Distribution of Hot-Stamped Part Using FE-Simulation Coupled with Quench Factor Analysis

    NASA Astrophysics Data System (ADS)

    2015-10-01

    In the hot stamping of boron-alloyed steel, the mechanical properties of hot-stamped parts have been predicted by many empirical models based on Kirkaldy's equation. Although these models are skillfully developed, there is still a need to precisely and easily predict the mechanical properties in the hot stamping process. Therefore, this study aims to suggest a novel method for the accurate prediction of the hardness distribution of hot-stamped parts by the use of finite element (FE)-simulations coupled with quench factor analysis (QFA). First, dilatometry of boron steel was performed at various cooling rates from 0.5 to 70 K/s using a dilatometer with a forced-air cooling system. The dilatometry test provided hardness data according to the cooling rates, which were used to determine the material constants ( K 1 to K 5) of the QFA and the time-temperature-property diagram of boron steel. Then, FE-simulation of hot stamping was conducted to obtain the cooling curves for blanks with thicknesses of 1.2 and 1.6 mm. The extracted results from the FE-simulation were used to predict the hardness distribution of the hot-stamped parts using QFA. Finally, a hot stamping experiment was performed to verify the predicted results and to examine the effect of the blank thickness on the cooling rates of a hot-stamped part. The predicted hardnesses for the parts were in good agreement with the measured values, within a maximum error of 4.96 pct.

  18. Dynamics of a Plant RNA Virus Intracellular Accumulation: Stamping Machine vs. Geometric Replication

    2011-01-01

    The tremendous evolutionary potential of RNA viruses allows them to thrive despite host defense mechanisms and endows them with properties such as emergence, host switching, and virulence. The frequency of mutant viruses after an infectious process results from the interplay between the error rate of the viral replicase, from purifying mechanisms acting after transcription on aberrant RNAs, and from the amplification dynamics of virus RNA positive (+) and negative (–) strands. Two extreme scenarios describing viral RNA amplification are the geometric growth, in which each RNA strand serves as template for the synthesis of complementary strands with the same efficiency, and the stamping machine, where a strand is reiteratively used as template to synthesize multiple copies of the complementary. The resulting mutation frequencies are completely different, being geometric growth largely more mutagenic than stamping machine. In this work we evaluate the contribution of geometric growth and stamping machine to the overall genome amplification of the plant (+)-strand RNA virus turnip mosaic virus (TuMV). By means of transfection experiments of Nicotiana benthamiana protoplasts with a TuMV cDNA infectious clone and by using strand-specific quantitative real-time PCR, we determined the amplification dynamics of viral (+) and (–) RNA during a single-cell infectious process. A mathematical model describing the amplification of each viral strand was fitted to the data. Analyses of the model parameters showed that TuMV (+) and (–) RNA amplification occurs through a mixed strategy with ?93% of genomes produced via stamping machine and only ?7% resulting from geometric growth.

  19. The stiffness and buckling behavior of panels with stamping-induced imperfections

    2011-08-01

    With the decrease of sheet thickness, the stiffness and buckling behavior of automobile body panel are more and more concerned. In this paper, the stiffness and buckling behavior of panels with stamping-induced imperfection is studied. Imperfections caused in drawing and springback are obtained by finite element analysis and introduced to define the initial state of the panel before indenting. The indenting procedure is simulated in ABAQUS Standard. In order to solve the buckling problem, a viscous pressure that is proportional to the relative velocity between surfaces is added artificially. For comparison, a simplified model in which imperfections are not considered is also established. Comparing the simulation results with the reference experiment, we find that the stamping-induced imperfections lead to a more severe oil canning phenomena under a buckling load, although they increase panel's initial stiffness a bit. Moreover, among all stamping-induced imperfections, the geometrical imperfection (surface deflection) is beneficial to increase panel's buckling load, and the material imperfections (residual stress and uneven thickness) help to decrease panel's buckling load and can make oil canning more severe during post-buckling. Influences of blank holder force, sheet thickness and material property on panel stiffness and buckling behavior are also studied. The work of this paper is beneficial to processing optimization, material selection, and reinforcement design for automotive exterior panels.

    The simplified (one step) method also called "inverse approach"(IA) for the numerical analysis of the stamping process has been continuously developed by the authors since the end of the eighties (1, 2, 3, 4). In the present paper we recall the main finite element formulation aspects of a robust IA analysis code, called FAST_STAMP, for an efficient estimation of the large elastoplastic strains (in particular the thickness strains) encountered in deep drawing operations. Our results will be presented and compared with others, obtained either from experiments or from incremental codes such as ABAQUS or STAMPACK. The presentation includes "math based" optimization algorithms and strategies for process parameter design. The cost functions and constraints are mainly express to reduce or control the thickness changes, the localized necking, the wrinkling tendency, the springback effects after forming. The design variables are describing the shape of the blank and the tools, the restraining forces due to drawbeads, material properties such as anisotropy coefficient and hardening exponent. Results will be presented to show the actual capabilities of the coupled analysis and optimization strategy with application to the design of stamping parameters.

    Itoh, Kouichi; Izu, Tetsuya; Ogata, Wakaha; Shimoyama, Takeshi; Takenaka, Masahiko

    This paper studies two types of documents in which an adversary can forge a signature on a chosen document. One type is that a nonce is padded on an input document. The time-stamp protocol is a good example of this type. Another is a structured document (such as PS or PDF) whose contents are described in a body part and information (such as generated time and a generator) are in a meta part. In fact, this paper shows how to forge a time-stamp, a signature on a PDF and an X.509 certificate by the extended forgery attack and numerical examples. Forged signature by the original or the extended attacks is only accepted by the clients whose length check of zero-field is loosely implemented. As a result, we found that the latest versions of Adobe's Acrobat and Acrobat Reader accept the forged time-stamp and the forged signature on a PDF document. Target of this attack is RSASSA-PKCS1-v1_5, which does not have provable security. We also show the expanded attack might forge the signature of RSASSA-PSS, which has provable security, when the length check of zero-field is omitted or loosely implemented.

    2012-04-01

    This article describes a new alternative approach to the fabrication of printed electrochemical sensors and biosensors based on the transfer of electrode patterns comprising common conductive and insulating inks from elastomeric stamps to a wide variety of rigid and flexible substrates. This simple, low cost, yet robust methodology is demonstrated to be well-suited for the formation of electrochemical sensors on non-planar substrates and large objects/structures, which have traditionally been off-limits to conventional screen printing techniques. Furthermore, the stamped electrode devices are shown to exhibit electrochemical performance that rivals that of their screen printed counterparts and display resilience against severe mechanical deformation. The stamp transfer approach is further extended to the demonstration of epidermal electrochemical sensors through the transfer of the electrode patterns directly onto the skin. The resulting sensors demonstrate a wide range of usability, from the detection of various physiological analytes, including uric acid on the skin, to the identification of residues originating from the handling of munitions and explosives. The migration of printable electrochemical sensors to non-conventional (non-planar and/or oversized) surfaces provides new opportunities within the personal healthcare, fitness, forensics, homeland security, and environmental monitoring domains.

  9. Dying and 'euthanasia'.

    PubMed

    Benatar, S R

    1992-07-01

    Medical progress, secularisation of life, growing acceptance of individual human rights (including the right to refuse medical treatment) and of shared decision-making in medicine have focused public attention on the ways in which life may, and perhaps even ought to, be allowed to end in our complex modern era. Intense and thoughtful bio-ethical debate over many years has 'unpacked' the many different understandings and interpretations of the word euthanasia. The consequent conceptual clarification together with recognition and acknowledgement of psychological implications has facilitated a growing rational consensus on openly accepting the withholding and withdrawing of treatment (under defined conditions) within the realm of sound medical practice. This is clearly distinct from assisted suicide and active euthanasia which are generally considered unacceptable perversions of medical practice. Given the ability to sustain life for prolonged periods, often in a permanent state of unconsciousness, the unrealistic expectations of some medical personnel and the lay public, the severe constraints on health care facilities in South Africa and the totally inadequate allocation of resources for highly effective medical treatments, it is appropriate to re-open public debate on the limits of 'striving officiously to keep alive' and on the distinction between 'allowing to die' and 'killing'. Concern that 'rational' arguments reflect moral decay rather than moral progress keeps the debate open and focuses attention on some 'slippery slope' consequences. PMID:1641720

  2. Fabrication of a GHz band surface acoustic wave filter by UV-nanoimprint with an HSQ stamp

    NASA Astrophysics Data System (ADS)

    Chen, Nian-Huei; Huang, Ju-Chun; Wang, Chiu-Yen; Huang, Fon-Shan

    2011-04-01

    A GHz band surface acoustic wave (SAW) filter was fabricated by UV-nanoimprint lithography (UV-NIL). The key techniques to produce a SAW filter include stamp and interdigital transducer (IDT) fabrication. For the stamp, high-aspect-ratio (AR) hydrogen silsesquioxane (HSQ)/ITO/glass stamps were first exposed by low e-beam dose. Adequate post-exposure bake, tetramethylammoniumhydroxide concentration, and etch time were utilized to pattern the HSQ stamps with a perfect vertical sidewall. HSQ/ITO/glass IDT stamps with widths in the range 46-168 nm were fabricated. The stamps were then cured with a novel step-like heating cycle as hard-bake. The modified HSQ stamps have a high hardness of 19 GPa. The HSQ/ITO/glass layered structure shows 80% transmittance at 365 nm UV light. Afterward, the IDT patterns were transferred on UV-curable resist/lithium niobate (LiNbO3) by UV-NIL at room temperature and low pressure. After removing the residual layer, Al/Ti films were deposited on UV-curable resist/LiNbO3. IDTs with widths in the range 62-219 nm and thickness of 20 nm could be obtained by following a lift-off process. The center frequency of 4.3-8.6 GHz and insertion loss of -14.1 to -61.7 dB of the SAW filters were measured by a network analyzer HP 8510C. The reactive ion etching step for residual layer elimination has significant implication for the electrical characterization of a SAW filter. The thorough removal of the residual layer not only ensures a clean interface between IDTs and LiNbO3 for SAW filters with minimum insertion loss, but also keeps intact IDT patterns for small center frequency shift.

  11. Reflections on death and dying.

    PubMed

    Holstein, M

    1997-10-01

    Americans simultaneously worry about dying and about being tethered to machines that keep them alive beyond a point when life has any meaning. People living with terminal illness often feel isolated from life around them and a burden on those they love; they feel uncertain that their deaths will be relatively free of pain and suffering and that their dignity will be compromised as little as possible. These failings can be remedied. Traditional hospice care and integrating palliative care into the general medical setting are important, but they cannot alone occasion a better dying. The medical community must re-imagine dying and reflect about ways to transform image into reality in practice and in training colleagues and successors. Physicians and others know how to provide care and even improve living when cure is unlikely; the harder task is to respect such care as profoundly as curing. The exigencies of modern medicine, where time is a budgetable commodity, makes caring well for dying patients difficult. Medicine cannot have hegemony over dying and cannot singularly offer people a better death, but it cannot absent itself either. The almost single-minded focus on decision making that has infused conversations about dying and death may divert attention from the attentiveness and loving relationships that are as vital as life's end as at its beginning. Medicine has "colonized" death: It has transformed it into a place where progress in staving it off may appear to be unlimited, and thus it encourages forgetting that death is part of the human condition. The task before medicine, and academic medicine in particular, is to transform death back into a human scale. With all that is available to delay death--but not to make it optional--the most important task is to recover humbleness before an awesome moment and be with the patient, one human being to another, knowing that dying is not always open to solutions.

  12. Micro-Contact Printing of Two Different Biomolecules in One Step Using Deformable Poly(dimethylsiloxane)-Based Stamp

    2008-06-01

    Patterning biomolecules at the micron or nano-scale presents a major challenge for the elaboration of integrated biochips. Among the different techniques that are emerging, Microcontact printing (µCP) appears as one of the most promising due to its simplicity and low cost. However, µCP exhibits a severe limitation because only one type of molecule can be deposited at a time using a poly(dimethyldiloxane) (PDMS) stamp. We present a new process called one-step-multiple-µCP (OSM-µCP) using a specific multilevel PDMS stamp which allows the patterning of two different molecules in one step. Our method based on the elastomeric properties of a PDMS stamp can print self aligned patterns of two different molecules by pressuring homogenously the top side of the stamp. The stamp levels inked by two different molecules contact the surface sequentially. OSM-µCP of two proteins, here bovin serum albumin BSA and streptavidin is demonstrated and this method can be applied to others couples of molecules. These results show that patterning biomolecules with OSM-µCP process opens new perspectives for soft lithography by enabling the fabrication of complex patterns of different molecules.

  13. Does the Food Stamp Program cause obesity? A realist review and a call for place-based research.

    PubMed

    DeBono, Nathaniel L; Ross, Nancy A; Berrang-Ford, Lea

    2012-07-01

    The high prevalence of obesity among low income groups has led some to question the role of food assistance programs in contributing to the problem. The USDA's Food Stamp Program (now known as the Supplemental Nutrition Assistance Program - SNAP) is the largest food assistance program in the United States with over 40 million participants. This paper employed systematic realist review methods to determine whether participation in the Food Stamp Program causes obesity and the causal pathways through which this relationship may exist. Findings indicate a more consistent positive relationship for women than for men, especially for women who are long term users of the program. All studies discussed the "food stamp cycle" and an "income effect" as explanations for the role of food stamps in increased obesity yet evidence for these factors is limited. Curiously, the research in this field does not address obesogenic environments and we suggest that the absence of an understanding of household behavior in local contexts is a significant impediment to the reform of the Food Stamp Program.

  14. Simulation and Evaluation of Phase Transformations and Mechanical Response in the Hot Stamping Process

    2007-05-01

    When producing thin ultra high strength steel components with the hot stamping process it is essential that the final component achieves desirable material properties. This applies in particular to passive automotive safety components. Often the desirable microstructure consists of a mix of martensite and bainite. Therefore, it is of great importance to accurately predict the final microstructure of the component early in the product development process. In this work a model to predict the austenite decomposition into ferrite, pearlite, bainite and martensite during arbitrary cooling paths for thin sheet boron steel is used. The decomposition model is based on Kirkaldy's rate equations and later modifications by Li et al. The modified model accounts for the effect from the added boron. The model is implemented as part of a material subroutine in the Finite Element Program LS-DYNA 970. Both the simulated volume fractions of micro-constituents and hardness profiles show good agreement with the corresponding experimental observations. The phase proportions affect both the thermal and the mechanical properties during the process of continuous cooling and deformation of the material. A thermo-elastic-plastic constitutive model including effects from changes in the microstructure as well as transformation plasticity is implemented in the LS-DYNA code. The material model is used in combination with a thermal shell formulation with quadratic temperature interpolation in the thickness direction to simulate the complete process of simultaneous forming and quenching of sheet metal components. The implemented model is used in coupled thermo-mechanical analysis of the hot stamping process and evaluated by comparing the results from hot stamping experiments. The results from simulations such as local thickness variations, hardness distribution and spring-back in the component show good agreement with experimental results.

  15. Over, under, or about right: misperceptions of body weight among food stamp participants.

    2008-09-01

    The purpose of this research was to investigate the associations between misperception of body weight and sociodemographic factors such as food stamp participation status, income, education, and race/ethnicity. National Health and Nutrition Examination Survey (NHANES) data from 1999-2004 and multivariate logistic regression are used to estimate how sociodemographic factors are associated with (i) the probability that overweight adults misperceive themselves as healthy weight; (ii) the probability that healthy-weight adults misperceive themselves as underweight; and (iii) the probability that healthy-weight adults misperceive themselves as overweight. NHANES data are representative of the US civilian noninstitutionalized population. The analysis included 4,362 men and 4,057 women. BMI derived from measured weight and height was used to classify individuals as healthy weight or overweight. These classifications were compared with self-reported categorical weight status. We find that differences across sociodemographic characteristics in the propensity to underestimate or overestimate weight status were more pronounced for women than for men. Overweight female food stamp participants were more likely to underestimate weight status than income-eligible nonparticipants. Among healthy-weight and overweight women, non-Hispanic black and Mexican-American women, and women with less education were more likely to underestimate actual weight status. We found few differences across sociodemographic characteristics for men. Misperceptions of weight are common among both overweight and healthy-weight individuals and vary across socioeconomic and demographic groups. The nutrition education component of the Food Stamp Program could increase awareness of healthy body weight among participants. PMID:18551119

    Die Geburtsstunde der Quantentheorie liegt hundert Jahre zurück, aber es dauerte ein Vierteljahrhundert, bis die neue Physik Wurzeln schlug und daraus die Quantenmechanik hervorging. Auf dem Weg dahin spielten die frühen Schulen der theoretischen Physik eine wichtige Rolle. Das erste dieser Zentren war die von Arnold Sommerfeld an der Münchner Universität gegründete Pflanzstätte für theoretische Physik. In Niels Bohrs 1921 eröffneten Institut für theoretische Physik gaben sich die hoffnungsvollen Nachwuchswissenschaftler die Klinke in die Hand, und in Deutschland war nach dem Ersten Weltkrieg die Universität Göttingen eine der ersten Adressen für moderne Physik. Der dortige Mentor war Max Born.

    We present a fabrication scheme called 'fork stamping' optimized for the dry transfer of individual pristine carbon nanotubes (CNTs) onto ferromagnetic contact electrodes fabricated by standard lithography. We demonstrate the detailed recipes for a residue-free device fabrication and in-situ current annealing on suspended CNT spin-valve devices with ferromagnetic Permalloy (Py) contacts and report preliminary transport characterization and magnetoresistance experiments at cryogenic temperatures. This scheme can directly be used to implement more complex device structures, including multiple gates or superconducting contacts.

  18. Time Stamp Attack in Smart Grid: Physical Mechanism and Damage Analysis

    E-print Network

    Gong, Shuping; Li, Husheng; Dimitrovski, Aleksandar D

    2012-01-01

    Many operations in power grids, such as fault detection and event location estimation, depend on precise timing information. In this paper, a novel time stamp attack (TSA) is proposed to attack the timing information in smart grid. Since many applications in smart grid utilize synchronous measurements and most of the measurement devices are equipped with global positioning system (GPS) for precise timing, it is highly probable to attack the measurement system by spoofing the GPS. The effectiveness of TSA is demonstrated for three applications of phasor measurement unit (PMU) in smart grid, namely transmission line fault detection, voltage stability monitoring and event locationing.

    For a car manufacturer, reducing the weight of vehicles is an obvious aim. Replacing steel by aluminium moves towards that goal. Unfortunately, aluminium's stamping numerical simulation results are not yet as reliable as those of steel. Punch-strength and spring-back phenomena are not correctly described. This study on aluminium validates the behaviour law Hill 48 quadratic yield criterion with both isotropic and kinematic hardening. It is based on the yield surface and on associated experimental tests (uniaxial test, plane tensile test, plane compression and tensile shearing).

  5. Development of a Press-Hardened Steel Suitable for Thin Slab Direct Rolling Processing

    NASA Astrophysics Data System (ADS)

    Lee, Jewoong; De Cooman, Bruno C.

    2015-01-01

    The thin slab casting and direct rolling process is a hot-rolled strip production method which has maintained commercial quality steel grades as a major material in many industrial applications due to its low processing cost. Few innovative products have however been developed specifically for production by thin slab direct rolling. Press hardening or hot press forming steel grades which are now widely used to produce structural automotive steel parts requiring ultra-high strength and formability may however offer an opportunity for thin slab direct rolling-specific ultra-high strength products. In this work, a newly designed press hardening steel grade developed specifically for thin slab direct rolling processing is presented. The press hardening steel has a high nitrogen content compared with press hardening steel grades produced by conventional steelmaking routes. Boron and titanium which are key alloying additions in conventional press hardening steel such as the 22MnB5 press hardening steel grade are not utilized. Cr is added in the press hardening steel to obtain the required hardenability. The properties of the new thin slab direct rolling-specific 22MnCrN5 press hardening steel grade are reviewed. The evolution of the microstructure and mechanical properties with increasing amounts of Cr additions from 0.6 to 1.4 wt pct and the effect of the cooling rate during die-quenching were studied by means of laboratory simulations. The selection of the optimum chemical composition range for the thin slab direct rolling-specific 22MnCrN5 steel in press hardening heat treatment conditions is discussed.

  10. Acting to let someone die.

    PubMed

    McGee, Andrew

    2015-02-01

    This paper examines the recent prominent view in medical ethics that withdrawing life-sustaining treatment (LST) is an act of killing. I trace this view to the rejection of the traditional claim that withdrawing LST is an omission rather than an act. Although that traditional claim is not as problematic as this recent prominent view suggests, my main claim is that even if we accepted that withdrawing LST should be classified as an act rather than as an omission, it could still be classified as letting die rather than killing. Even though omissions are contrasted with acts, letting die need not be, for one can let die by means of acts. The remainder of the paper is devoted to establishing this claim and addresses certain objections to it. PMID:24320715

    Dying is universal, and death should be a peaceful time. Myriad comfort measures are available in the last weeks before life ends. Discussions about end-of-life issues often suffer from lack of informed opinion. Palliative care experts have identified specific somatic and psychological sources of distress for dying patients and their loved ones. Pain, shortness of breath, nausea and vomiting, and fear of abandonment contribute substantially to both physical and psychological discomfort toward the end of life. Simple, effective methods exist for relieving those symptoms. Knowledge about the natural events associated with dying and an informed approach to medical and psychological interventions contribute to systematic and successful comfort care. We describe the origin of physical and psychological distress at the end of life and provide strategies for alleviating many of the discomforts. PMID:7571591

    Isothermal die forging is one of near net-shape metal-forming technologies. Strict control of billet temperature during isothermal die forging is a guarantee for the excellent properties of final product. In this study, a new method is proposed to accurately control the billet temperature of complex superalloy casing, based on the finite element simulation and response surface methodology (RSM). The proposed method is accomplished by the following two steps. Firstly, the thermal compensation process is designed and optimized to overcome the inevitable heat loss of dies during hot forging. i.e., the layout and opening time of heaters assembled on die sleeves are optimized. Then, the effects of forging speed (the pressing velocity of hydraulic machine) and its changing time on the maximum billet temperature are discussed. Furthermore, the optimized forging speed and its changing time are obtained by RSM. Comparisons between the optimized and conventional die forging processes indicate that the proposed method can effectively control the billet temperature within the optimal forming temperature range. So, the optimized die forging processes can guarantee the high volume fraction of dynamic recrystallization, and restrict the rapid growth of grains in the forged superalloy casing.

    Das Kapitel der modernen Herzchirurgie mit Einsatz der Herz-Lungen-Maschine am Menschen beginnt am 6. Mai 1953, als J. Gibbon bei einer 18-jährigen Patientin einen angeborenen Defekt in der Vorhofscheidewand verschließt [1]. Mit ersten experimentellen Versuchen zur extrakorporalen Zirkulation begann Gibbon bereits in den 30er Jahren des 20. Jahrhunderts. Die Grundlage für die heute gebräuchliche Rollerpumpe schufen Porter und Bradley mit ihrer "rotary pump“, welche sie 1855 zum Patent anmeldeten. Diese Pumpe wurde von DeBakey und Schmidt modifiziert und entspricht im Wesentlichen noch der heute sich im Routinebetrieb befindlichen Rollerpumpe [2].

    The shape optimization of realistic, 3-D automotive components is discussed. The integration of the major parts of the total process: modeling, mesh generation, finite element and sensitivity analysis, and optimization are stressed. Stamped components and solid components are treated separately. For stamped parts a highly automated capability was developed. The problem description is based upon a parameterized boundary design element concept for the definition of the geometry. Automatic triangulation and adaptive mesh refinement are used to provide an automated analysis capability which requires only boundary data and takes into account sensitivity of the solution accuracy to boundary shape. For solid components a general extension of the 2-D boundary design element concept has not been achieved. In this case, the parameterized surface shape is provided using a generic modeling concept based upon isoparametric mapping patches which also serves as the mesh generator. Emphasis is placed upon the coupling of optimization with a commercially available finite element program. To do this it is necessary to modularize the program architecture and obtain shape design sensitivities using the material derivative approach so that only boundary solution data is needed.

    Springback is a common phenomenon in sheet metal forming since the elastic recovery of the internal stresses is induced after removal of the tooling. The numerical analysis of springback is a complicated time-consuming job and its result is greatly effected by a type of the yield function, finite elements used and the constraint condition for eliminating a rigid body motion. In this paper, optimization of the draw-bead force is carried out utilizing the response surface method in order to reduce springback and improve shape accuracy of a deep drawn product. In the optimization process, the tendency of springback is evaluated qualitatively without springback simulation usually done with the implicit solving scheme. Instead of springback simulation, the amount of stress deviation along the thickness direction in the deep drawn product is used as an indicator of springback. The stamping process is analyzed for a front side member formed with advanced high strength steel (AHSS) sheets such as DP60. The analysis procedure fully covers the binder-wrap, stamping, trimming and springback processes with the commercial elasto-plastic finite element code LS-DYNA 3D. The effect of the restraining force of draw-beads is confirmed with the decreased stress deviation. The analysis result shown in the final springback simulation demonstrates that the present analysis provides a guideline for controlling the evolution of springback based on the finite element simulation of complicated auto-body members.

    Surface-enhanced Raman spectroscopy (SERS) is a spectroscopic technique, where Raman scattering is boosted primarily by enhanced electric field due to localized surface plasmon resonance (LSPR). With advances in nanofabrication techniques, SERS has attracted great attention for label-free molecular sensing and imaging. However, the practical use of SERS has often encountered an inherent issues regarding a molecule transfer step where target molecules need to be within the close proximity of a SERS-active surface by either mixing with nanoparticles or coating onto surface-bound nanostructures. To address this issue, we have developed stamping surface-enhanced Raman spectroscopy (S-SERS) for label-free, multiplexed, molecular sensing and large-area, high-resolution molecular imaging on a flexible, non-plasmonic surface without solution-phase molecule transfer. In this technique, a polydimethylsiloxane (PDMS) thin film and nanoporous gold disk SERS substrate play the roles as molecule carrier and Raman signal enhancer, respectively. After stamping the SERS substrate onto the PDMS film, SERS measurements can be directly taken from the "sandwiched" target molecules. The performance of S-SERS is evaluated by the detection of Rhodamine 6G (R6G), urea, and its mixture with acetaminophen (APAP), in physiologically relevant concentration range, along with corresponding SERS spectroscopic maps. S-SERS features simple sample preparation, low cost, and high reproducibility, which could lead to SERS-based sensing and imaging for point-of-care and forensics applications.

    Forming limit curves(FLCs) are commonly used for evaluating the formability of sheet metals. However, it is difficult to obtain the FLCs with desirable accuracy by experiments due to that the friction effects are non-negligible under warm/hot stamping conditions. To investigate the experimental errors, experiments for obtaining the FLCs of the AA5754 are conducted at 250°C. Then, FE models are created and validated on the basis of experimental results. A number of FE simulations are carried out for FLC test-pieces and punches with different geometry configurations and varying friction coefficients between the test-piece and the punch. The errors for all the test conditions are predicted and analyzed. Particular attention of error analysis is paid to two special cases, namely, the biaxial FLC test and the uniaxial FLC test. The failure location and the variation of the error with respect to the friction coefficient are studied as well. The results obtained from the FLC tests and the above analyses show that, for the biaxial tension state, the friction coefficient should be controlled within 0.15 to avoid significant shifting of the necking location away from the center of the punch; for the uniaxial tension state, the friction coefficient should be controlled within 0.1 to guarantee the validity of the data collected from FLC tests. The conclusions summarized are beneficial for obtaining accurate FLCs under warm/hot stamping conditions.

    The federal government has estimated the prevalence of household "food insecurity" and "food insecurity with hunger" since 1995. Early observers believed that the new measure could be used to assess and improve the Food Stamp Program (FSP). Ten years of research have tempered the initial optimism. The prevalence of food insecurity with hunger (12.3% of all low-income households in 2004) is much higher among food stamp participant households (18.6% in 2004) than among low-income nonparticipant households (10.1% in 2004), due to strong self-selection effects. Households facing greater hardship are more likely to join the program. This article reviews 6 types of nonexperimental research designs that have been used to address the self-selection problem. The results have been inconclusive and the authors have warned against drawing causal inferences from their research. Ethical random-assignment research designs may be required to satisfy the intense policy interest in measuring the antihunger impact of the FSP. The most promising ethical research designs would test the effects of offering eligibility to households that are currently ineligible or offering increased benefits to households that are currently eligible for small benefit amounts.

    In this paper, the upper-bound solutions proposed by Eivani and Karimi Taheri [Comp. Mater. Sci. 42 (2008) 14] to calculate processing force and evaluate die corner angle ? formation in terms of tribology and die configurations during cold single pass equal channels angular pressed metals with constant flow stress were extended to work-hardening metals processed by two passes according to route A by using the Swift model combined to von Mises isotropic plasticity criterion. Also, adiabatic heat equation was coupled to solutions to express the final temperature of the workpiece. For that, thermomechanical properties of a hot-dip galvanized interstitial-free (IF) were considered and its behavior under pressing was evaluated to non-hardening and work-hardening conditions in all performed analyses. By including work-hardening in the models and for the critical friction factor of 0.4, theoretical predictions after single pass showed a decreasing of die corner angle and pressing force predictions and increasing of effective plastic strain and end temperature for all friction conditions and tooling geometries evaluated. In addition, after second pass, these responses showed higher values. Finally, with the proposed upper-bound models it was possible to analyze the dependency of angle ?, effective plastic strain, pressing load and sample temperature with the instantaneous workpiece height at the entry surface of deformation zone.
