微圆孔缺陷相互作用与空间位置分布的细观分析

THE EFFECT OF INTERACTION AND SPATIAL DISTRIBUTION OF CIRCULAR VOID DEFECTS

文[1]建立了微缺陷相互作用的一般理论模式，给出了包含周期分有微圆孔缺陷的损伤体的有效弹性柔度张量。本文是文[1]的续编，着重讨论了激圆孔之间的相互作用和微圆孔的空间分布对损伤体有效性质的影响．同时，本文对相应的理论问题进行了数值模拟，理论预测与数值模拟结果吻合较好．本文研究表明，损伤体有效性质的各向异性特征明显地依赖于微圆孔的空间位置分布特征．

Being a continuation to paper[1],this paper centers on the influence of the interactionof voids with each other and their spatial distribution on the effective properties of the dam-aged body. Meanwhile,numerical simulation is made for the corresponding theoretical prob-lem. The theoretical prediction and the numerical simulation results coincide with each otherquite satisfactorily. It is proved that fhe anisotropy of the effective property of damaged bodyconsiderably relies on the spatical distribution of microvoids.
