Abstract:

基于增量塑性损伤理论与纤维增强金属层板疲劳裂纹扩展唯象方法,推导出在拉-压循环加载下,纤维增强金属层板疲劳裂纹扩展速率预测模型。并通过玻璃纤维增强铝合金层板在应力比R=-1,-2的疲劳裂纹扩展实验对预测模型进行验证。结果表明,纤维增强铝合金层板疲劳裂纹扩展的压载荷效应分为两种情况:在有效循环应力比RC>0时,表现为压载荷对铝合金层所承受残余拉应力的抵消作用;当RC<0时,表现为压载荷抵消残余拉应力后,对纤维增强铝合金层板金属层的塑性损伤,对疲劳裂纹扩展存在促进作用。纤维铝合金层板疲劳裂纹扩展的压载荷效应不可忽略,本文中得出的在拉-压循环加载下疲劳裂纹扩展速率预测模型与实验结果符合较好。
