Abstract
The boundary integral equation (BIE) method was formulated to evaluate the stress intensity factors of a crack approaching a curvilinear hole in an anisotropic plane under arbitrary loadings. The kernel function used in the BIE formulation has already taken the crack into consideration and the BIE discretization applies only to the hole. Thus the crack tip singularity is included inherently in the BIE solution and the possible numerical difficulty when simulating the crack is avoided. Numerical results considered only a crack approaching a circular or elliptical hole. The results reveal that the effect of anisotropy on stress intensity factors may be significant under certain types of loadings.
