摘要
提出了适用于电子束或X射线辐照、爆炸和高速碰撞等问题的弹-塑性流体动力学数值模拟计算的一种新自由面格式。一些数值模拟计算的结果表明,所给出的新自由面格式明显优于目前一直沿用的Richtmyer格式。
The auther suggested a new free-surface scheme which is suitable for the numerical calculation of elastic-plastic flow such as electron-beam or X-ray radiation, high velocity impact and blast. Some numerical examples are given which show that the present free-surface scheme is more suitable than Richtmyer's for solving thermal-mechanical effects of material subjected to electron-beam or X-ray pulse radiation.
