正交各向异性截锥壳的非线性动静力响应及稳定

The Nonlinear Dynamic and Static Response and Dynamic Stability for Orthotropic Truncated Conical Shells

分析了均布载荷作用下正交各向异性截锥壳的非线性动、静力响应。首先推导出了系统的控制方程；接着利用Ｇａｌｅｒｋｉｎ法及Ｎｅｗｍａｒｋ法得到了问题的动力和静力响应曲线及在多种情况下动力稳定临界载荷的数值解。

The nonlinear dynamic and static response are anaiyzed for urthotropic truncated conical shells under uniform distributed loading , The governing equations of the system are founded . The approximate solutions of the dynamic and static response and the dynamic bucking loads are nbtaincd by using Galerkin and Newmark method .
