Based on the elasto-viscoplastic constitutive equation, the history of stress and strain is analyzed during uniaxis tension under oscillatory loading. 基于弹粘塑性本构关系,讨论了附加振动时单轴拉伸的应变及应力变化过程。
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。
