摘要 通过复变函数论的方法,得到了横观各向同性体的轴对称裂纹表面受阶跃载荷作用下的位错分布函数的解析解.对具有任意的自相似指数的轴对称动态裂纹扩展问题进行求解,导出解析解的一般表达式.使得考虑的问题相应地简化,并具有一定的普遍性. By the method of theory of complex functions, analytical solution to dislocation distribution function of the edges of an axially symmetric crack subjected to unit - step loads for transversely isotropic body were obtained. Axisymmetric dynamic crack propagation problems with arbitrary index of self - similarity were solved, and the general expressions of the analytical solutions were educed. The considered problems become simple and possess an evident universality.
