从平衡热力学不可逆系统出发，用非线性粘弹塑性运动强化模型来模拟高温合金材料的应变控制热机械疲劳循环特性．讨论了温度变化和应变循环的相位关系，循环相关和时间相关热机械疲劳损伤机制，蠕变和疲劳间的相互作用．在建立本构关系和状态方程时，均考虑了温度变化所产生的影响．在确定模型各个参数时，使用等温力学试验和疲劳试验数据，为用等温疲劳研究成果分析变温疲劳性质，开辟了新的途径．
Based on the irreversible equilibrium thermodynamic system, a nonlinear viscoelastic-plastic kinetic hardening model was used to simulate the strain-controlled thermomechanical fatigue cycle of superalloy. The phase relationship between temperature change and strain cycle, the mechanism of cyclic and thermal-mechanical fatigue damage, and the interaction between creep and fatigue are discussed. In establishing the constitutive relationship and the equation of state, the effects of temperature changes are taken into account. In the determination of various parameters of the model, isothermal mechanical tests and fatigue test data were used to analyze the temperature-dependent fatigue properties based on the research results of isothermal fatigue and opened up new ways.
