| 摘 要： | 本文首先讨论了王仁等提出的结构塑性动力屈曲的能量准则,将其含义作了某种延伸,使之适用于直接屈曲以外其它类型的动力屈曲。然后,用推广了的能量准则讨论任意冲击速度下圆柱壳的塑性动力屈曲。已有的有关圆柱壳径向冲击屈曲结果可归结为本文特例。

| Abstract: | The dynamic plastic buckling of cylindrical shells subjected to general initial impulsive velocity is studied and the formulas of critical mode numbers n_(cr) and critical impulsive velocity q_0 are obtained based on an extended energy criterion. The results are in good agreement with the previous theoretical results obtained by Abrahamson and Ru. |
