Response surface method is introduced simply and applied to the structural shape optimization of two-dimension continuum. Combined with finite element, the approximate expressions of constraints functions are fitted by a series of structural analysis. The complex analytical sensitivity analysis is avoided. The programme of shape optimization is empoldered under the platform MSC Patran with Patran Command Language (PCL). The examples illustrate the feasibility and efficiency of RSM.
