Shakedown Estimation Methods for Perforated Spherical Cover under Cyclic Internal Pressure
摘要
Abstract
Based on the finite element program Abaqus,the elastic shakedown limit of perforated spherical cover considering the main effect factors,such as opening radius and opening position,was investigated system atically according to the simplified shakedown limit algorithm under cyclic internal pressure,and the corresponding shakedown evaluation method was further proposed.Results presented that the proposed shakedown estimation method shows good reliability for shakedown evaluation of perforated spherical cover under cyclic internal pressure.关键词
