摘要：
In this manuscript, we study a primal hybrid finite element method for two dimensional linear elasticity problem. We derive a priori error estimates for both primal and hybrid variables. The rate of convergence of the method is independent of the Lame parameters, which illustrates the robustness of the method. Numerical experiments are presented to validate the theoretical findings.
