strain amplitude effect

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 effect is observed under cyclic loading conditions with small strain amplitudes, and is manifest as a dependence of the viscoelastic storage modulus on the amplitude of the applied strain.

效果观察与应变振幅小，在循环加载条件下，表现为粘弹性储能模量的依赖应用应变的振幅。

Through the stress-controlled test the effect of the amplitude ratio, the average stress, stress amplitude and loading rate on the ratcheting strain and strain range are studied.

通过应力控制，研究了幅值比，平均应力，应力幅，加载率对棘轮应变以及棘轮应变幅的影响。
