摘要
对 1Cr1 8Ni9Ti不锈钢材料进行了两种不同加载路径的多轴非比例应力循环棘轮效应试验 ,研究了应力路径形状、平均应力及其历史对棘轮效应的影响 ,揭示了此材料多轴非比例棘轮效应的一些特征及其原因 。
The ratchetting experiments of 1Cr18Ni9Ti stainless steel under multiaxial nonproportional cyctic loading are performed. Two different stress paths are chosen for the tests. The ratchetting features and the influence of the shape of stress paths, mean stress and the mean stress history are investigated. Some results obtained are expected to be useful in advancing the constitutive model of ratchetting.
