摘要
根据复合材料层板疲劳损伤机理,首先建立数学模型,然后运用宏观断裂力学的方法分析、推导出了在基体损伤破坏下正交层板的疲劳损伤寿命的预测公式,最后通过算例进行了验证。
Based on the fatigue damage mechanism of composite laminates,first,a model with transverse cracks is put forward,then,the formula of fatigue damage life of composite laminates method is induced by the micro fracture mechanics,finally,the numerical result is obtained.
