Stress Minimization of the Pressure Vessel by Optimal Shape Design

This study proposes an optimal shape of the pressure vessel by the self-developed simplified conjugated gradient method (SCGM) for minimizing the Von Mises stress of this pressure vessel. The finite element analysis built from the ANSYS parametric design language is optimized by SCGM. The results are validated by the previous study. This study proves that the optimization of geometry can reduce the stress concentration of the pressure vessel effectively. It will benefit the design of the nuclear reactor for safe consideration. In addition, this proposed optimal method will build an effective way to simplify the engineering design procedure.
