(energy1)Development of Modeling Tools for Joining of Hydroformed Multi-Component Lightweight Structures

Develop computational methods and simulation tools for predicting weld durability of hydroformed aluminum alloy extrusions and to gain an understanding of the effects of severe deformations associated with hydroforming on the weld microstructure, residual stress state, and distortions in welded assemblies. Develop numerical procedures to simulate hydroforming in a parallel computing environtment and model welding operations
