| 摘 要： | 从疲劳过程中材料显微组织结构的变化特征、疲劳损伤的非线性效应等方面进行分析与论证，提出了不存在一般意义上的“等效损伤状态”的观点，采用高－低和低－高两组循环载荷下的损伤累积试验，对传统意义上的“等效损伤状态”下的剩余寿命试验进行了验证。

| 关 键 词： | 疲劳损伤；损伤等效；剩余寿命 |

| Abstract: | According to the analysis on the variation of the microstructure of the material subjected to cyclic loading and nonlinear essence of cumulative fatigue damage, the present paper proposed the point that no general "equivalent damage state" exists. Test results of cumulative fatigue damage under High Low and Low High two level loading as well as test results of residual fatigue life under traditional"equivalent damage state" have given a positive support to this viewpoint. |
