摘要: 采用解析法、矩方法和Monte Carlo法等方法,计算了电子束在硬铝靶材中的能量沉积.计算表明,3个结果基本符合.根据得出的能量沉积结果和一维应变弹塑性流体动力学模型,计算了电子束热激波在硬铝靶材中的传播,并将其应力峰值的计算值与实测值进行了比较.

关键词: 电子束, 能量沉积, 热激波, 材料响应

Abstract: Three methods——analysis method,moment method and Monte-Carlo method——are used to calculate the energy deposition of electron beam in LY-12AL,and the results agree well with each other.According to these results and the one dimension elastic-plastic fluid dynamics model, thermal shock wave resulted in the high energy deposition in LY-12AL is calculated. Peaks of the thermal shock wave accords with the results from experiments.

Key words: electron beam, energy deposition, thermal shock wave, material response
