摘要
基于所建立的Findley、Matake以及法向应力疲劳分析模型对在法向载荷和剪切载荷下不锈钢430F柱状测试样条进行疲劳分析。通过与疲劳计算表达式解析值比较表明,Findley、Matake以及法向应力疲劳分析模型都能较准确的预测不锈钢430F柱状测试样条的疲劳使用因子,对柱状测试样条的疲劳预测提供指导。
The fatigue analysis of circular specimen stainless steel 430F was studied based on established Findley, Matake and normal stress fatigue analysis models under conditions of normal load and shear load. By comparing with the analytical values according to fatigue analytical expressions, it is found that Findley, Matake and normal stress fatigue analysis model can accurately predict the fatigue usage factor for circular specimen stainless steel 430F, which can provide guidance and reference for the fatigue prediction of circular specimen.
