提出了一种能考虑非比例硬化和动态应变时效对轴扭热机械循环载荷下响应应力影响的统一粘塑性本构模型。该模型在随动强化规则中考虑了旋转因子和非比例强化系数。提出了动态应变时效影响因子，进一步修正了随动硬化准则，使其能够考虑特定应变速率和温度条件下的动态应变时效。在等温和非等温轴向扭转循环载荷作用下，该模型的模拟结果与实测数据吻合较好。
A unified viscoplastic constitutive model, which can consider the influences of non-proportional hardening and dynamic strain aging on the responded stress, was proposed under axial-torsional thermo-mechanical cyclic loading. In the proposed model, the rotation factor and the non-proportional hardening coefficient were considered in the kinematic hardening rule. And the dynamic strain aging influence factor was also proposed to further modify the kinematic hardening rule, which can consider the induced dynamic strain aging under special strain rate and temperature conditions. Moreover, the simulation using the proposed model can achieve a better fit with the measured data under isothermal and non-isothermal axial-torsional cyclic loadings.
