A recovery-type error estimator for the extended finite element method based on singular+smooth stress field splitting

Ródenas, J.J.; González-Estrada, O.A.; Taráncón, J.E.; Fuenmayor, F.J. (John Wiley & Sons, 2008)

[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 ...
Improvement of the Superconvergent Patch Recovery technique by the use of constraint equations: the SPR-C technique

Ródenas, J.J.; Tur, M.; Fuenmayor, F.J.; Vercher, A. (John Wiley & Sons, 2007)

[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 ...
Superconvergent patch recovery with constraints for three-dimensional contact problems within the Cartesian grid Finite Element Method

Navarro-Jiménez, José-Manuel; Navarro-García, Héctor; Tur Valiente, Manuel; Ródenas, Juan José (John Wiley & Sons, 2020-03-30)

[EN] The superconvergent patch recovery technique with constraints (SPR-C) consists in improving the accuracy of the recovered stresses obtained with the original SPR technique by considering known information about the ...
