摘要
在相关理论和假设的基础上，给出了自由状态下阶梯形质量分布金属圆柱壳体在侧向非对称脉冲载荷下的变形和运动方程，针对矩形脉冲载荷得出塑性响应解及临界断裂破坏判据，理论预测与实验结果吻合较好。
This paper uses a series of theories and hypothesis for stepped cylindrical shells with free-free end subjected to lateral local distributed impulsive loading.Solutions for the deformation and velocity profile of the shell are obtained.Compared with experimental results,the theory predicted plastic response and the critical rupture impulse are performed well for the rectangular pressure pulse.
