Certification of projection-based reduced order modelling in computational homogenisation by the Constitutive Relation Error
Pierre Kerfriden, Juan José Ródenas García, Stéphane Pierre-Alain Bordas
In this paper, we propose upper and lower error bounding techniques for reduced order modelling applied to the computational homogenisation of random composites. The upper bound re…
Report: Error estimation of recovered solution in FE analysis
Enrique Nadal Soriano, Octavio Andrés González Estrada, Juan José Ródenas García +1
The recovery type error estimators introduced by Zienkiewicz and Zhu use a recovered stress field evaluated from the Finite Element (FE) solution. Their accuracy depends on the qua…
Mesh adaptivity driven by goal-oriented locally equilibrated superconvergent patch recovery
Octavio Andrés González Estrada, E. Nadal, J. J. Ródenas +3
During the last decade there has been an increase on the use of goal-oriented error estimates which help to quantify and control the local error on a quantity of interest (QoI) tha…
Enhanced error estimator based on a nearly equilibrated moving least squares recovery technique for FEM and XFEM
J. J. Ródenas, Octavio Andrés González Estrada, F. J. Fuenmayor +1
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. We explore th…
Efficient recovery-based error estimation for the smoothed finite element method for smooth and singular linear elasticity
Octavio A. González-Estrada, Sundararajan Natarajan, Juan José Ródenas +2
An error control technique aimed to assess the quality of smoothed finite element approximations is presented in this paper. Finite element techniques based on strain smoothing app…
On the role of enrichment and statical admissibility of recovered fields in a-posteriori error estimation for enriched finite element methods
Octavio A. González-Estrada, Juan José Ródenas, Stéphane P. A. Bordas +3
Purpose: This paper aims at assessing the effect of (1) the statical admissibility of the recovered solution; (2) the ability of the recovered solution to represent the singular so…
