| 摘 要： | 首次将内时理论应用于屈曲问题，由具有非保守性质的内时虚功变分方程，研究了柱壳在纯弯曲下的塑性屈曲响应。结果显示了卡门－钱学森关于屈由“跳跃理论”的性质，证实了湘利关于塑性屈曲临界载荷不唯一的提法，表明了塑性屈曲破坏是一个相继屈曲的过程。

| Abstract: | To advance the applications of endochronic theory in plastic buckling problems ,the plastic buckling responses of cylindrical shell were studied by using nonconservative endochronic variational equations.The properties of solution are in line with that of Karman-Tsien's jumping theory.The point of view of non-single buckling loads given by Shanley was comfirmed. |
