Boundary element method for crack analysis in two-dimension anisotropic solid

The derivation and calculation of crack problems by using boundary element method (BEM) are presented. When calculating the node displacement, the displacement boundary integral equations are superseded by stress boundary integral equation, then a simplifier computational process is generated. Stress field and displacement field around the straight crack are calculated by using both BEM and Abaqus methods. Furthermore, the stress intensity factor (SW) was achieved from the solution. A good agreement is found between the BEM and Abaqus results, proved that BEM is a reliable method to calculate crack problems.
