| 摘 要： | 将经典全量理论作了推广，考虑了应力状态对拉压性能不同材料塑性行为的影响，并用其计算了环板的应力分布，结果表明，应力状态塑性体积变形对环板的环向应力影响较大，因此，不能将拉压性能不同材料简化成体积不可压缩的理想材料。

| Abstract: | Under the condition of considering the influence of the stress station on the plastic behavior of the materials with different behavior in tension and compression, the constructive equation of deformation theory for the ideal materials of same yield stresses under tension and compression is generalized, and the modified constructive equation is used to analyze the stress distribution of annular plate. It is shown that the influence of the stress state and plastic deformation of volume on the circumferential stress is significant. Therefore, the materials with different behavior under tension and compression cannot be simplified as the ideal materials who's volume can't be compressed. |
