| 摘 要： | 首先,指出Lemaitre等提出的高周疲劳损伤演化方程只适用于等效应力循环为等幅的加载情形.然后,基于等效应力循环为不等幅的加载情形,推导出适用于高周疲劳的损伤演化方程,说明上述等幅加载情形的损伤演化方程只是高周疲劳损伤演化方程的一个特例,且后者的结果更具一般性.

| Abstract: | First, it is pointed out that the damage law of evolution for high cycle fatigue advanced by Lemaitre is only applied to the loading of equal amplitudes on equivalent stress cycles. Then, it is obtained that the damage law of evolution can be applied to high cycle fatigue based on the loading of non-equal amplitudes on equivalent stress cycles. The damage law of evolution on equal amplitudes loading is the special example of the damage law of evolution for high cycle fatigue. |
