【摘要】 基于纤维增强复合材料疲劳机理和试验数据,文中给出一个描述纤维增强复合材料拉—拉疲劳的S—N曲线模型。此模型同时考虑复合材料受载方向的静抗拉强度、纤维静强度、疲劳载荷应力比等诸多因素对S—N曲线的影响,且模型中所用参数容易得到更多还原

【Abstract】 Based on the fatigue mechanism and experimental date of fiber-reinforced plastic(FRP),a S—N curve model was presented,which describes the fatigue behavior of FRP under tensile-tensile loading. The effects of laminate static strength, fiber static strength and loading ratio to S—N curve were analyzed and all parameters could be gotten conveniently in the model.更多还原
