THE APPLICATION OF RSM IN SHAPE OPTIMIZATION OF TWO-DIMENSIONAL CONTINUUM
响应面方法在二维连续体形状优化中的应用

The response surface method is applied to the structural shape optimization of a two-dimensional continuum, combined with FEM, with the approximate expressions of constraints functions being fitted, and the complex analytical sensitivity analysis avoided. The program of the shape optimization is developed under the platform MSC/Patran with Patran Command Language (PCL). The examples illustrate the feasibility and efficiency of RSM.
