[EN] A new stress recovery procedure that provides accurate estimations of the discretization error for linear elastic fracture mechanic problems analyzed with the extended finite element method (XFEM) is presented. The ...
[EN] The superconvergent patch recovery (SPR) technique is widely used in the evaluation of a recovered stress field sigma* from the finite element Solution sigma(fe). Several modifications of the original SPR technique ...
