The Classical Pressure Vessel Problem for Void Damage Materials

Institute of Engineering Mechanics, Nanchang University, Nanchang 330029, P. R. China

摘要: 本文根据微弹性结构线性理论研究了带空洞损伤的压力容器问题．解答是准静态的,其应力场为古典弹性力学关于球体对称压力容流问题应力解答,位移场和损伤场具有由于考虑损伤而表现出体积粘弹性特点．

Abstract: In this paper,the classical pressure vessel problem for void damage materials is studied from the theory of mncrostructure in linear elasticity.The solutions are quasi static.The Stress distribution is predicted by isotropic linear elasticity.The displacement and damage fields exhibit a volumetric viscoelasticity induced by considering material damage.
