| 摘 要： | 文中根据Von Mises屈服准则及Pradtl-Reuss增量关系，推导出了理想弹塑性材料、四节点板壳单元的增量本构关系，根据上述理论和利用有限元程序ANSYS实现了对管节点的弹塑性大挠度分析，并对三个管相贯节点作了弹塑性大挠度的全过程分析。

| Abstract: | Based on the ideal elastic-plastic mechanical model and the Von-Mises yield criterion,the constitutive relation of the four-node shell element is inferred.Inelastic,large deflection finite element analysis of the tubular joints is completed with the finite-element package program ANSYS,and inelastic,large deflection finite element analysis are completed on there tubular joints with author's method.The results show that analysis method employed is proved to be validly and correctly. |
