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 ...
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 ...
Comparison of KI calculation methods

Qian, Guian; González Albuixech, Vicente Francisco; Niffenegger, M.; Giner Maravilla, Eugenio (Elsevier, 2016-05)

This paper compares different numerical methods for mode I stress intensity factor (SIF) calculations. Both 2D and 3D models are used to calculate KI for the compact tension specimens. J-integral and interaction integral ...
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 ...
Estimación y acotación del error de discretización en el modelado de grietas mediante el método extendido de los elementos finitos

González Estrada, Octavio Andrés (Universitat Politècnica de València, 2010-02-19)

El Método de los Elementos Finitos (MEF) se ha afianzado durante las últimas décadas como una de las técnicas numéricas más utilizadas para resolver una gran variedad de problemas en diferentes áreas de la ingeniería, como ...
On the role of enrichment and statical admissibility of recovered fields in a-posteriori error estimation for enriched finite element methods

González Estrada, Octavio Andrés; Ródenas, J.J.; Bordas, Stéphane Pierre Alain; Duflot, Marc; Kerfriden, Pierre; Giner Maravilla, Eugenio (Emerald, 2012)

Purpose The purpose of this paper is to assess the effect of the statical admissibility of the recovered solution and the ability of the recovered solution to represent the singular solution; also the accuracy, local and ...
Relevant factors affecting the direction of crack propagation in complete contact problems under fretting fatigue

Marco, Miguel; Infante-Garcia, Diego; Diaz-Alvarez, Jose; Giner Maravilla, Eugenio (Elsevier, 2019-03)

[EN] In fatigue problems, an accurate estimation of the propagation direction is important for life prediction. We identify the most relevant factors that affect the crack orientation during the propagation stage of fretting ...
