Efficient and accurate stress recovery procedure and a posteriori error estimator for the stable generalized/extended finite element method

Summary This paper presents a new stress recovery technique for the generalized/extended finite element method (G/XFEM) and for the stable generalized FEM (SGFEM). The recovery procedure is based on a locally weighted L2 projection of raw stresses over element patches; the set of elements sharing a...
