| 摘 要： | 较详细地介绍了疲劳寿命预测的剩余刚度，强度和疲劳模量模型，并且指出了这些方法的主要不足。在此基础上提出了一种基于疲劳损伤过程能量衰减的剩余能量模型，以及进行复合材料结构疲劳寿命预测的二元方法的构想。

| Abstract: | The residual strength,residual stiffness and residual fatigue module of the fatigue life predictionhave been summarized in detail.The limitations of these modules have been analyzed.In this paper,a residualenergy dissipation module on basis of the energy degradation evolution rule in the fatigue damage process has beenproposed,furthermore,the dichotomy idea on the fatigue life prediction of the composite material structures andcomponents has been introduced in accordance with the local energy equivalent theory. |
