摘要：
In this paper, we consider the linear elasticity problem based on the Hellinger-Reissner variational principle. An O(h(2)) order superclose property for the stress and displacement and a global superconvergence result of the displacement are established by employing a Clement interpolation, an integral identity and appropriate postprocessing techniques.
