Abstract
An extension of the contour integral method (CIM) for the computation of stress intensity factors for loaded cracks is presented. Numerical solutions of the two-dimensional linear elasticity equations are computed with the p-version of the generalized finite element method. Polynomial enrichment functions as well as enrichment with near crack tip asymptotic expansion are used. The robustness of the formulation with respect to the size of the extraction domain and the convergence of the computed stress intensity factors and energy release rate are analysed.
