Simulation result of the experiment shows that unloading and recovery process of PTCS is not consistent with the local stress redistribution and concentration.It can be divided into four phases:1.local stress unloads first in the middle of PTCS;2. stress continues to unload near the incident bar.3.Stress continues to unload near the transmission bar,the first and second layer PT buckling rumple disappear;4.the whole PTCS vibrates elastically.

对具体冲击实验的数值模拟结果表明：相变柱壳的卸载恢复过程在柱壳结构中是不均匀的，伴随着壳体局部应力释放和局部应力集中，可以分为以下四个阶段：1、柱壳中部发生弯曲变形的壳体应力首先释放，2、靠近入射杆端的壳体应力继续释放，3、靠近透射杆端的壳体应力释放，第一层与第二层相变屈曲皱褶消失，4、柱壳整体弹性振动。
