| 摘 要： | 采用复变函数论的方法,对不同复合材料界面上的裂纹扩展问题进行了研究,并根据任意的自相似指数的断裂动力学问题,对裂纹表面某点受阶截荷和集中载荷作用的问题进行了自相似求解,给出了该问题的解析表达式。应用该法可以迅速地将所研究问题转化为Riemann-Hilbert问题,然后利用Mskhelishvili方法进行求解,最后求得在不同载荷作用下该问题的闭合解析解答。

| Abstract: | By using the theory of complex functions, the general representations of the analytical solutions are reduced for crack problems of arbitrary index of self-similarity propagating along the interfaces between dissimilar composite materials subjected to step load and concentrated load. The problems of Riemann-Hilbert can be formulated correctly and their analytical solutions are obtained by using the method of Mskhelishvili and closed analytical solutions are obtained about this problems under various loads. |
