| 摘 要： | 基于理想弹塑性模型,对拉压模量不同的厚壁球壳进行弹塑性分析.在不同内压作用下,对厚壁球壳进行了弹性分析、弹塑性分析,最后进行塑性极限分析,并求解厚壁球壳各个状态下的应力及位移的大小.分别讨论了弹塑性边界位置不同时,球壳内壁开始屈服的弹性极限压力及球壳整个截面完全屈服的塑性极限压力.

| Abstract: | According to the perfect elastoplastic model,the elastoplastic of thick spherical shell with the different elastic modulus of tension and compression was analyzed.Under the action of different internal pressures,the discussion of thick spherical shell was made from elastic analysis,elastoplastic analysis,until plastic limit analysis.The values of stress and displacement of spherical shell in the varied states were obtained.The elastic limit pressure of shell with the inner side of spherical shell yielded an... |
