Abstract

This paper presents a single-domain boundary element method (BEM) for linear elastic fracture mechanics analysis in the two-dimensional anisotropic material. In this formulation, the displacement integral equation is collocated on the un-cracked boundary only, and the traction integral equation is collocated on one side of the crack surface only. A special crack-tip element was introduced to capture exactly the crack-tip behavior. A computer program with the FORTRAN language has been developed to effectively calculate the stress intensity factors of an anisotropic material. This BEM program has been verified having a good accuracy with the previous researches. Furthermore, by analyzing the different anisotropic degree cracks in a finite plate, we found that the stress intensity factors of crack tips had apparent influence by the geometry forms of cracks and media with different anisotropic degrees.
