Abstract
In this article, we couple design sensitivity analysis and numerical optimization with process simulation to improve the design of castings and weldments. We first derive expressions for explicit sensitivity analysis of weakly coupled thermal stress systems. In the first of two example problems thermal analysis is used to determine an optimal riser design for a steel hammer casting. In the second example, thermal and elasto-plastic stress analyses are performed on a butt-welding process, which is then optimized to control residual stress and distortion.
