Abstract
The stress intensity factors (SIFs) for the cracks emanating from a hole in an anisotropic finite plate are analyzed by the boundary collocation method (BCM). This method is a semi-analytic and a semi-discrete method. The stress functions are assumed such that not only the governing equations of the anisotropic plate in the domain, but also the free boundary conditions on the crack surfaces and the stress singularity at the crack tip have been satisfied. Therefore, only the boundary conditions on the hole and the boundaries of the plate need to be considered, and they can be satisfied approximately by the least square method. Some numerical examples are given and a series of advantages of the method are demonstrated.
