In the case of homogeneous Dirichlet boundary conditions, the new a posteriori error estimator is reliable and locally efficient, whereas for non-homogeneous Dirichlet boundary conditions, we derive an a posteriori error estimator that is reliable and satisfies a quasi-efficiency bound. Numerical experiments illustrate the performance of the corresponding adaptive algorithms and support the theoretical results.engReconocimiento-NoComercial-SinObraDerivada 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Linear elasticityMixed finite element methodStabilizationA posteriori error estimatesjournal articleopen access
