摘要：
Computer analysis of the welding process can now be reasonably carried out in 3D for many simple geometries. This allows direct comparison with more conventional 2D approximations for common heavier-walled joints. Multipass plate butt weld examples are presented, using a range of analysis techniques based on commercial finite element software and the results compared to one another. This project has application to a larger effort to understand the relationship between far-field displacement control boundary conditions and weld residual stress fields. Heat source, high temperature material property, constitutive and element birth and death modeling are also addressed.
