摘要 利用对 316L不锈钢多轴非比例加载低周疲劳的试验结果 ,对现有的多轴低周疲劳寿命估算方法进行了讨论 ,基于 316L不锈钢非比例加载低周疲劳的微观机理 ,选择最大剪应变以及应变路径的非比例度作为损伤参量 ,建立了基于临界面方法的新的非比例加载低周疲劳寿命估算公式 ,利用新的非比例加载低周疲劳寿命估算公式对寿命的预测结果表明 :新的寿命估算公式对剪切型破坏的 316L与 316LN不锈钢及拉伸型破坏的 30 4不锈钢非比例加载低周疲劳寿命预言能力比现有的临界面方法精确 . The test results of nonproportional low cycle fatigue under multiaxial loading of 316L stainless steel are used. The present multiaxial low cycle fatigue life prediction methods are discussed. Based on the micromechanism of multiaxial low cycle fatigue under nonproportional loading of 316L stainless steel,maxium shear strain and nonproportionality of strain paths are considered as damage parameters of low cycle fatigue. At the same time,the fatigue criterion based on critical plane methods is proposed. The results of fatigue life prediction by using the new low cycle fatigue life criterion under nonproportional loading show that the new fatigue life criterion predicted better fatigue life of shear type failure material 316L and 316LN stainless steel and tensile failure material 304 stainless steel than the other fatigue life criterion did.
