| Abstract: | Analytic sensitivity analysis technology for the boundary element method (BEM) is presented, combined with a shape optim ization system for structural analysis. A shape optimization was done for an ela stomer under planar stress, based on this new algorithm. A multi-object problem was studied as an illustrative example for the programmer, using weighted summing m ethod. The result is feasible. |
