The performance of abrasive waterjet depends on the impact velocity of abrasive. 磨料水射流的性能主要取决于磨料颗粒的冲击速度。
For a impact process with a normal impact velocity, the control equation for RKPM was deduced based on a small strain and incremental elasto-plastic constitutive law. 针对冲击速度较低的情况,假设冲击过程为小应变,并引入弹塑性增量本构关系,推导出冲击过程的再生核质点法计算控制方程。
