M´ ethode des ´ el´ ements finis mixte duale pour les probl` emes de l’´ elasticit´ e et de l’´ elastodynamique: analyse d’erreur ` a priori et ` a posteriori `

We derive an a posteriori error estimation for the discrete duality finite volume (DDFV) discretization of the stationary Stokes equations on very general twodimensional meshes, when

In the following subsections, we study the evolution of the error related to q ∇ (u) (results in Section 5.1.1, associated adjoint problem described in Fig. 8), with respect to

• A posteriori error estimation tools used to compute the error • The computation of the bound is deterministic. • The second moment of the quantity of interest can be bounded –

We introduce a residual-based a posteriori error estimator for contact problems in two and three dimensional linear elasticity, discretized with linear and quadratic finite elements

Purpose  This paper aims at assessing the eect of (1) the statical admissibility of the recovered solution; (2) the ability of the recovered so- lution to represent the

In Farhloul and Manouzi [1], these authors have introduced a mixed finite el- ement method for problem (0.1) based on the introduction of σ = |∇ u | p − 2 ∇ u as a new unknown and

Here, we present an error estimation technique for enriched finite element approxi- mations that is based on an equilibrated recovery technique, which considers the stress
