The experimental results revealed that an appropriate overlay thickness can not only use laser energy effectively but also provide optimal peakpressure of shock waves.
实验表明，采用一定厚度的约束层，既能有效利用激光能量，又能获得较大的激光冲击波峰压；

The artificial viscosity can control the oscillations trailing the shock front, but it also weakened the peakpressure.
人工粘性能够较好地抑制冲击波压力计算中出现的数值振荡，但同时也引起了冲击波峰值的衰减。

The purpose of this paper is to examine the calculation method of direct shock wave peakpressure.
