| 中文摘要 | 基于复变函数方法,给出了两种正交异性体结合面间半无限长裂纹的自相似解,本文方法可以把复杂边界条件转化为简单的Keldysh-Sedov混合边值问题,迅速地得到问题的闭合解,并给出实例,通过对其叠加, 可以得到任意复杂半无限裂纹问题的解析解,最后给出应力强度因子的图表。; Based on the theory of complex functions, self-similar solutions of semi-infinite interface crack between two kinds of orthotropic materials are given. Complex boundary conditions can be reduced to simple Keldysh-Sedov problems and analytical solutions can be derived immediately. Moreover, by superposition the analytical solutions for arbitrary complex semi-infinite crack can be obtained. At last, examples are given and stress intensity factors are presented graphically. |
