Based on the elasto-viscoplastic constitutive equation, the history of stress and strain is analyzed during uniaxis tension under oscillatory loading. 基于彈粘塑性本構關(guān)系，討論了附加振動(dòng)時(shí)單軸拉伸的應變及應力變化過(guò)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. 針對沖擊速度較低的情況，假設沖擊過(guò)程為小應變，并引入彈塑性增量本構關(guān)系，推導出沖擊過(guò)程的再生核質(zhì)點(diǎn)法計算控制方程。
