| 摘 要： | 采用塑性动力屈曲能量准则，对圆柱壳非均匀局部径向冲击下的塑性动力屈曲进行了研究。文中分别采用弹性的角弹簧和位移弹簧模拟非屈曲部分对屈曲部分的影响，推导了有关模态和临界速度的冲击公式，并与有关的实验结果进行了比较，分析了两种边界对塑性动力屈曲的影响。

| Abstract: | In this paper,the energy criterion is used to study the dynamic plastic buckling of cylindrical shells,which are locally subjected to a nonuniform radial impulsive loading.Elasticboundary conditions are used to model the influence of the non-buckling parts of the shell on thebuckling parts.Calculating formulas for the number of mode and critical velocity are given andthe calculating results are compared with that of experimental.The effects of two kinds of bound-ary conditions on the plastic buckling are analysed. |
