摘要 研究了超载对LY12CZ铝合金疲劳裂纹起始寿命的影响,得出了超载前后带存活率的疲劳裂纹起始寿命的定量表达式.提出了在变幅载荷下,铝合金切口件疲劳裂纹起始寿命概率分布的预测方法,并进行了实验验证.结果表明这种预测方法是切实可行的. Overload effect on fatigue crack initiation is studied for the LY12CZ aluminum alloy. The expressions for survivability are obtained for notched specimens with and without overload. Probability distribution of fatigue life is predicted and substantiated for variable amplitude loading.
