摘要
给出了全应力张量空间中的光滑粒子流体动力学方法插值公式 ,利用该方法编制程序对高速碰撞问题进行了数据模拟 ,给出了正碰撞和斜碰撞 2个算例 ,得到了合理的模拟结果。表明该方法可以运用于冲击力学问题的数值模拟计算。
The smoothed particle hydrodynamics equations that include the entire stress tensor are formulated. The SPH method program is used in simulating the problems of high velocity impact. Two calculating models, which include normal impact and sloping impact, are simulated, and the results are rational. It is demonstrated that SPH method can be applied to solving impact problems.
