In this paper, a simple way is proposed to improve the overall performance of the four-node plane stress element. Numerical examples are given. Results show that the accuracy of both stress and displacement for a coarse mesh is raised by the proposed method. The reason is clearly given. The problem of mesh size dependent may be overcome in a certain degree if integration points are properly selected.
