摘要
由于纤维增强复合材料内部结构固有的复杂性，目前还没有一种理论和方法能很好地解决带缺陷的复合材料的断裂问题。本文发展了一种宏微观结合模型，用有限元方法计算复合材料的断裂问题，得到了一些有意义的结果。
Because the conventional approach to fracture analysis is not capable of coping with the degree of complexity required for composite materials, a proper fracture mechanics analysis method for composite material is necessitated. This paper proposes a macro micro model which divides a composite material containing a flaw into local and global regions and deals with the problem in each region by different methods. By means of the finite element analysis, more useful results are obtained.
