带空洞损伤的古典压力容器问题

The Classical Pressure Vessel Problem for Void Damage Materials

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．

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