In the present research, the self-heating phenomenon in laminated composites under fatigue loading was studied. The generated-dissipated energy (GDE) model was developed to calculate the generated energy due to the viscoelastic nature of the matrix, and the dissipated energy through the convection and conduction mechanisms. To consider the effects of irreversible fatigue failure modes in laminated composites, the GDE model was coupled with the progressive fatigue damage (PFD) model. By coupling these two models, the self-heating (S–H) model was developed to simulate the self-heating temperature rise in laminated composites under fatigue loadings. An experimental program was conducted to validate the present model. The temperature at the surface of laminated composites was monitored by an infrared thermography camera during the fatigue tests. The experimental results show that the present model can precisely predict the self-heating temperature rise in composite specimens with an arbitrary stacking sequence under fatigue loading conditions.

在目前的研究中，研究了疲劳载荷下层压复合材料的自热现象。开发了生成耗散能量 (GDE) 模型来计算由于基体的粘弹性而产生的生成能量，以及通过对流和传导机制的耗散能量。为了考虑层压复合材料中不可逆疲劳失效模式的影响，GDE 模型与渐进式疲劳损伤 (PFD) 模型相结合。通过耦合这两个模型，开发了自热 (S-H) 模型来模拟疲劳载荷下层压复合材料的自热温升。进行了一个实验程序来验证本模型。在疲劳试验期间，通过红外热像仪监测层压复合材料表面的温度。
