...: the welding temperature field is solved by a transient thermal analysis, and subsequently, a nonlinear elastic plastic stress analysis is carried out. The effect of the unexpanded zone length with reference to the expanded zone of the joints is investigated. The results indicate that welding after...

...Si Y. Lee; Steve J. Hensel; Chris De Bock The engineering design of disposal of the high level waste (HLW) packages in a geologic repository requires a thermal analysis to forecast the temperature history of the packages. Calculated temperatures are used to demonstrate compliance with criteria...

... distribution pattern is modeled and considered for the weld pool design. Elastic-plastic material properties at various temperatures are also considered for simulation. A detailed finite element analysis is carried out to predict the welding residual stress. In this, thermal analysis is carried out for actual...
