A mixed virtual element method for a pseudostress-based formulation of linear elasticity
Cáceres, Ernesto; Gatica, Gabriel N.; Sequeira, Filander (Elsevier B.V., 2019)In this paper we introduce and analyze a mixed virtual element method (mixed-VEM) for a pseudostress-displacement formulation of the linear elasticity problem with non homogeneous Dirichlet boundary conditions. We follow ... -
A priori and a posteriori error analyses of a pseudostress-based mixed formulation for linear elasticity
Gatica, Gabriel N.; Gatica, Luis F.; Sequeira, Filánder A. (Computers and Mathematics with Applications vol.71 no.2 585-614 2016, 2016-01-02)In this paper we present the a priori and a posteriori error analyses of a non-standard mixed finite element method for the linear elasticity problem with non-homogeneous Dirichlet boundary conditions. More precisely, the ... -
A RTk - P-k approximation for linear elasticity yielding a broken H(div) convergent postprocessed stress
Gatica, Gabriel N.; Gatica, Luis F.; Sequeira, Filander (Universidad Nacional, Costa Rica, 2015)We present a non-standard mixed finite element method for the linear elasticity problem in R-n with non-homogeneous Dirichlet boundary conditions. More precisely, our approach is based on a simplified interpretation of the ...
