The collision of two hemishells is analyzed where one hemishell is clamped and the other impinges on the inner surface of the clamped hemishell. A model of rigid-perfectly plastic behavior is proposed for the flow of material in the region of contact. An expression relating velocity and deformation is obtained and compared with the results of experiments.

The evaporator recycle streams of nuclear waste tanks may contain waste in a chemistry and temperature regime that exceeds the current corrosion control program, which imposes temperature limits to mitigate caustic stress corrosion cracking (CSCC). A review of the recent service history found that two of these A537 carbon steel tanks were operated in ...
The liquid waste chemistry control program is designed to reduce the pitting corrosion occurrence on tank walls. The chemistry control program has been implemented, in part, by applying engineering judgment safety factors to experimental data. However, the simple application of a general safety factor can result in use of excessive corrosion inhibiting agents. The required use of excess corrosion ...

Until recently, the Yukon River was a major obstacle in constructing a roadway to the oil-rich North Slope of Alaska. But on Oct 10, 1975, that obstacle was hurdled when the first bridge across the Yukon was open to traffic. This new $30,000,000 crossing is located 100 miles northwest of Fairbanks. The remote location, extremely cold climate, and other environmental factors called for unusual ...
