摘要: 简要讨论了强脉冲离子束与金属靶材料相互作用的理论模型，以此为基础应用数值计算的方法模拟计算了离子能量为1.0 MeV和300 keV，束流密度分别为10 A/cm2、50 A/cm2、100 A/cm2的质子束与金属铝靶材料相互作用时的热力学效应，给出了铝在辐照后内部的温度分布、温度梯度分布，以及温度变化速率（加热速率与冷却速率）、热激波的产生与传播过程及与应力等模拟计算结果。Abstract: In this paper, a model for the interaction of intense pulsed ion beams (IPIB) with metallic targets is briefly described. Then the thermal-mechanical effects on the aluminum target irradiated by the IPIBs with ion energy of 300 keV and 1.0 MeV, current density of 10, 50, 100 A/cm2 are simulated numerically. The calculation results, i.e., the stress, temperature, temperature gradient distributions, heating and cooling rates and elastic waves and shocks are presented and discussed.
