A constitutive model was developed on the base of Ohno–Wang kinematic hardening model Int. J. Plast. 9 (1993 375, 391. In the developed model, the rate dependence of the material was reflected by a viscous term; the steady cyclic flow was reflected by the evolution of kinematic hardening rules with critical state of dynamic recovery developed by Ohno and Wang Int. J. Plast. 9 (1993 375, 391; the cyclic hardening was only characterized by the evolution of isotropic hardening and an evolution rule of isotropic hardening with a term of dynamic recovery was used; the effect of loading history on the ratcheting was also considered by introducing a fading memorization function for maximum plastic strain amplitude into the model.

基于Ohno-Wang模型建立了一个新的、考虑材料的率相关特性的本构模型，模型中通过具有临界面的随动硬化律来反映稳态的循环流动，并通过带动态恢复项的各向同性硬化演化率来反映循环硬化的影响以及采用最大塑性应变幅值的衰减记忆函数来反映棘轮行为的加载历史记忆效应。
