| 摘 要： | 应用Ｅｓｈｅｌｂｙ等效夹杂理论和Ｍｏｒｉ－Ｔａｎａｋａ的平均化方法建立片状纤维复合材料的细观损伤力学理论，将损伤模型处理为随机“连桥”问题，给出这种宏观正交各向同性材料的９个独立弹性常数的显式表达式，并研究基体材料中孔洞形状及体积含量和裂纹密度对材料整体弹性性能的影响。

| Abstract: | A damage theory of micromechanics for ribbon reinforced composite is established by means of Eshelby's equivalent inclusion principle and Mori-Tanaka's mean field method. The nine components of the overall elastic moduli of the composite with randomly oriented pores in matrix are derived explicitly. The results are given in terms of the void shape and concentration or crack density. |
