潜艇加肋圆柱壳壳板轴对称破坏模式的极限状态分析

The Limit Analysis for the Axisymmetric Failure of the Submarine Ring-stiffened Cylindrical Shells

通过对弹性基础梁的复杂弯曲进行塑性极限状态分析,得到了表示潜艇加肋圆柱壳在静水外压下,壳板轴对称变形的极限状态判据和极限载荷的计算方法。并用模型试验对计算方法进行了验证。

By using the plastic limit analysis on the complicated bending of a beam on the elastic foundation, a new limit state criterion and a new calculating method of limit load on the ax- isymmetric deformation of the submarine ring -stiffened cylindrical shells subjected to hydro- static pressure are obtained in this paper. Finally, this caculating method is verified by means of model tests.
