| 摘 要： | 研究了复合材料层板疲劳过程中的累积应变演化规律，建立了以累积应变为基础的非线性积累损伤法则，实验结果表明：文中提出的累积应变方法能够较好地反映加载次序效应，准确地预测了复合材料层板在两级载荷下的疲劳寿命。 |
| 关 键 词： | 复合材料；疲劳损伤；加载次序 |

| Abstract: | The evolution law of cumulative strain is studied during the fatigue damage of the fiber reinforced laminated composites, and a nonlinear fatigue cumulative damage rule, which based on the cumulative strain, is suggested. The results of two stress level tests show that the predicted values of fatigue life using this method are in good agreement with the experimental data. |
| Keywords: | composite materials fatigue damage loading sequence. |
