Accurate recovery-based error upper bounds for the extended finite element framework

Ródenas, J.J.; Gonzalez-Estrada, O.A.; Díez, P.; Fuenmayor Fernández, Francisco-Javier (Elsevier, 2010)

[EN] This paper introduces a recovery-type error estimator yielding upper bounds of the error in energy norm for linear elastic fracture mechanics problems solved using the extended finite element method (XFEM) The paper ...
Enhanced error estimator based on a nearly equilibrated moving least squares recovery technique for FEM and XFEM

Ródenas, J.J.; González Estrada, Octavio Andrés; Fuenmayor Fernández, Francisco Javier; Chinesta, F. (Springer Verlag, 2012)

In this paper a new technique aimed to obtain accurate estimates of the error in energy norm using a moving least squares (MLS) recovery-based procedure is presented. In the techniques based on the superconvergent patch ...
Equilibrated patch recovery error estimates: simple and accurate upper bounds of the error

Díez, P.; Ródenas, Juan José; Zienkiewicz, Olgierd C. (John Wiley & Sons, 2007)

[EN] This paper introduces a new recovery-type error estimator ensuring local equilibrium and yielding a guaranteed upper bound of the error. The upper bound property requires the recovered solution to be both statically ...
