| 摘 要： | 循环塑性应变能作为疲劳损伤用于疲劳过程研究已经多年，但其演化规律的数学描述至今尚不完善。本文在分析循环塑性应变能循环相关特点的基础上，建立了它的损伤演化方程，并利用实验结果对该二元非线性方程进行了拟合。

| Abstract: | It is a long time since the cyclic plastic strain energy was used as fatigue variability to study fatigue failure,but it is still lack of mathematical expression about cyclic plastic strain energy evolutional rule.Based on analysis of the cyclic relativity rule of cyclic plastic strain energy,the damage evolutional equation is given in this paper,and this non-linear equation is processed by means of experimental data. |

| Keywords: | cyclic plastic strain energy fatigue damage non-linear |
