摘要
本文采用王仁等提出的塑性动力屈曲的能量准则讨论了圆柱壳在不均匀的外部径向冲击下的塑性动屈曲问题，获得了屈曲的占优波数公式及临界冲击速度公式，初步的实验证明本文的结论是合理的。同时进一步证明该能量准则的有效性。
The dynamic plastic buckling of cylindrical shells subjected to nonuniform external irnpulsiveloads is analysed with the dynarnic buckling criterion propcoed by Wang and Ru. The formulae of per-ferred mode numbers and critical loads of buckling are given and proved by the experimental resultsgiven by Lindberg and Florence. We also conclude that the energy criterion proposed by Wang and Ruis a suitable method for dealing with the buckling problems discussed by this paper.
