Development of a Computer Aided Weld Design Tool

Abstract

Contributed to the development of a Lagrangial thermo-mechanical process optimization approach. The methodology was demonstrated in the optimization of the thermal tensioning process for the minimization of welding residual stress elimination of buckling distortion. Developed eigenvalue sensitivity analysis capabilities for the prediction and elimination of buckling distortion in large welded structures. Initiated research on the coupled multi-scale thermo-mechanical process modeling of large structures. The approach combines adaptivity and domain decomposition for both temporal and spatial multi-scale problems.
