THE APPLICATION OF RSM IN SHAPE OPTIMIZATION OF TWO-DIMENSIONAL CONTINUUM

The response surface method is applied to the structural shape optimization of a two-dimensionalcontinuum, combined with FEM, with the approximate expressions of constraintsfunctions being fitted, and the complex analytical sensitivity analysisavoided. The program of the shape optimization is developed under theplatform MSC/Patran with Patran Command Language (PCL). The examplesillustrate the feasibility and efficiency of RSM.
