摘要
通过对纤维增强复合材料层板疲劳过程中能量耗散的不可逆过程的分析,并考虑不同加载次序,建立了一种以有效能耗为基础的非线性疲劳损伤累积法则。
The irrecoverable process of energy dissipation is analyzed during the fatigue damage of the fiber reinforced laminated composites. After thinking about the different loading sequence, a nonlinear fatigue cumulative damage rule, which is based on the effective hysteresis energy dissipation, is suggested. The present cumulative damage rule is able to correctly describe the loading order effect, about which a rigorous theoretical and experimental proof is provided.
