摘要

本文研究了具有三维随机分布的两相夹杂体:球体相互平行的空洞和不同取向的增强平行刚性球体短纤维。利用有效场法，给出了有效刚度四阶张量的数值表达式。比较了夹杂体的同时嵌入和顺序嵌入。损伤演化由修改后的Vakulenko?内时热力学的S方法。对有效弹性对称问题作了简要说明。将理论结果应用于反应器不锈钢AISI 316H的损伤弹粘塑性应变。

On inelasticity of damaged quasi-rate-independent orthotropic materials

The paper deals with a body having a random 3D-distribution of two-phase inclusions: spheroidal mutually parallel voids as well as differently oriented reinforcing parallel stiff spheroidal short fibers. By the effective field approach the effective stiffness fourth-order tensor is formulated and found numerically. Simultaneous and sequential embeddings of inclusions are compared. Damage evolution is described by modified Vakulenko?s approach to endochronic thermodynamics. A brief account of the problem of effective elastic symmetry is given. The results of the theory are applied to the damage-elasto-viscoplastic strain of reactor stainless steel AISI 316H.
