| Abstract: | The nonlinear is the one of fundamental characters of materials. The problem of material nonlinear in structure calenlation is mainly materialized by the basic theory of the finite element method, The three-dimension nonlinear program coded is used to realize the nonlinear of material and compared with the elastic-plastic analytical solution through a concrete example. The correctness of program is validated by the result, the character of material nonlinear can be truly reflected by the nonlinear finite element method. |
