摘要
用连续介质损伤力学的方法推导了非线性损伤发展方程 ,考虑了加载过程应力与损伤的完全耦合效应 ,计及了疲劳加载循环周内和循环周间损伤累计非线性效应的完全非线性疲劳累计损伤 。
Getting non linear fatigue expanding equation by continuous medium damage mechanics,considering completely couple of stress and fatigue in loaded procedure, and considering completely non-linear fatigue cumulative damage in one circle and between circles of fatigue loading,the decreasing law of remnant strength and critical damage value of metals are obtained.
