We prove that the proposed a posteriori error estimators are both reliable and efficient. Numerical experiments confirm these theoretical properties and illustrate the ability of the corresponding adaptive algorithms to localize the singularities and large stress regions of the solutions.engReconocimiento-NoComercial-SinObraDerivada 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Mixed finite elementAugmented formulationA posteriori error estimatorLinear elasticityjournal articleopen access
