摘要: 采用能量沉积解析法、材料低压本构关系及一维应变弹塑性流体动力学模型，对闪光二号电子束辐照硬铝产生的热激波的传播规律进行了数值模拟。结果表明，计算值与实测值基本符合。Abstract: We have made numerical simulations of the propagation of thermal shock waves induced in aluminum alloys irradiated by the electron beam on FLASH-Ⅱ, adopting an analytic method of the energy deposition, the constitution relation of material in low-pressure zone and one-dimension strain model of the elastic-plastic hydrodynamics. The computed results show that the computed values are in basically agreement with the measured.
