We previously discussed the crack tip singularities of various kinds of open crack meeting at the interfaces of different isotropic materials for plane problems. Based on these results, this study is concerned with singularities near the tip of an arbitrary open crack terminating at the interface of isotropic and anisotropic materials. Using the eigenfunction-expansion method of Williams, the crack tip singularities for mode I and mode II are computed. The characteristic determinant is derived by the boundary conditions and interface continuity conditions, and is solved directly using Mullers'method, which computes algebraic equations of high degree. The theoretical process of the analysis and some numerical results represented by figures are given.
