In this model, a new kinematic hardening equation was used; the non-proportionality, the effect of temperature and memorization for the maximum plastic strain amplitude were also considered.
该模型给出了一个新的背应力演化方程,引入了非比例度参量,并且还考虑了最大塑性应变幅值记忆效应和温度效应的影响。
The values of plastic strain energy density are affected by the plastic strain amplitude and change with the cycle numbers.
合金的塑性应变能密度受应变幅的影响且具有循环相关性;
With the increase of the grain size of H68 brass, the critical plastic strain for the onset of serrations increases while the maximum stress amplitude of serrations decreases.
