摘要：
This paper discusses the sensitivity analysis for a finite element model during shape optimization design for a pressure vessel. The derivative of a stiffness matrix and various load rankings with respect to design variables are obtained. Because the information resulting from the finite element analysis is fully utilized in this method, the programs are greatly simplified so that it becomes possible to carry out the shape optimization with comparatively more variables. The conclusion is illustrated by an example.
