英文摘要：

The finite element method for plane elasticity problems has the characteristics of high precision and simple rules,but the programming is relatively complex. Based on the analysis of the model of plane elasticity problems,the finite element specific algorithm and flow chart are presented,and a plane elasticity problem with pure displacement is given as an example to illustrate the numerical results and the validity.
