| Abstract: | 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. |
| Keywords: | self-similar orthotropic body semi-infinite interface crack fracture dynamics |
