The material of the ring-stiffened circular cylindrical shell will yield in plastic flection before the hull structure fails. 摘要耐压圆柱壳结构发生失稳时，壳体结构因为材料达到屈曲极限而发生了塑性屈曲变形。
Tills paper is concerned with the thermal and mechanical response of a spheric shell subjected to an internal pressure and the irradiation of a high power laser beam. 强激光辐照导弹壳体材料使其软化甚至熔融击穿，导致导弹壳体结构强度降低，在气动载荷和惯性载荷的共同作用下，导弹壳体可能产生结构失稳。
