摘要
采用简化材料状态方程,用1维特征线方法计算了激光驱动冲击波在多层材料中稳定传播的距离。计算结果与用1维三温激光-靶耦合JB程序的数值模拟结果进行了比较,二者符合得比较好。通过计算发现:冲击波在Au中的稳定传播距离受基底厚度的影响很大,稳定传播距离随基底厚度的增加先增大后减小。
Laser driven shock wave stability of propagation in impedance match target was studied using one dimension characteristic line method. In addition, one dimension three temperature laser-target coupling JB program was used to simulate it. It was compared with simplified equation of state. The results of the two methods agree well. The calculation results show that shock wave stability of propagation in Au depends closely on the thickness of the Al base.
