Abstract
Recently developments in numerical methods such as the Extended Finite Element Method (X-FEM) and the Extended Boundary Element Method (X-BEM) have significantly improved the accuracy in linear elastic fracture mechanics (LEFM) problems. Nevertheless, the postprocessing involved in the calculation of the Stress Intensity Factors still presents a computational burden. The most usual SIF evaluation techniques are the J-integral or the more general Interaction Integral (M-integral), which may require considerable computational resources of the order of those required to obtain the solution of the LEFMproblem. A direct approach, where the SIFs are revealed in the solution vector, has been developed by [1] for isotropic materials and is further extended to anisotropic materials in this work.
