| Abstract: | The structure in this paper is analyzed by the finite element software MSC/Nastran in nonlinear elastic-plastic solution,and the relationship of the structural stress and residual stress compared with yielding limit of the material has been examined.The results of the analysis fit the experimental results well,which confirms the accuracy of the nonlinear elastic-plastic solution about the engineering structures by using the software. |
