摘要

摘要: 激光辐照下充压柱壳局部受热，最终导致充压柱壳上激光加载区发生鼓包和爆裂现象。作者用有限元方法数值模拟了激光辐照下柱壳的变形，计算出的应力、应变场显示光斑中心处是最有可能发生爆裂的地方，结论与实验结果相符。同时，根据计算结果，对激光加载初期发生鼓包现象的原因作了分析。

Abstract: When intensive laser beam irradiated on a cylinder tank wall, bulge and rupture will take place at the area laser loaded. In this paper, the finite element method is used to simulate the deformation. The stress and strain field calculations predict that the center of the laser beam irradiated region is the most dangerous where rupture will take place. This result is in good agreement with the experiment.
