In light of Hu and Zhang's result of conforming finite element for symmetric tensors in any dimension, we propose a mixed finite element method for linear elasticity with nonconforming symmetric stress approximation in lower order. This numerical approximation contains a small number of degrees of freedom so that it is easy to implement. Furthermore, our mixed finite element methods can be constructed on arbitrary simplicial grids for any space dimension in a unified fashion, which is neat theoretically.
