| 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。经过初步实验,证明本文的结论是合理的,并进一步证实了该能量准则的有效性。

| Abstract: | The dynamic plastic buckling of cylindrical shells subjected to ununiform external impulsive loads is analysed with the dynamic buckling criterion proposed by Wang and Ru. The formulas of preferred mode numbers and critical loads of buckling are given and proved by the experimental results given by Lindberg and Florence. We also conclude that the energy criterion proposed by Wang and Ru is a suitable method for dealing with the buckling problems discussed in this paper. |
