摘要
通过对两种不锈钢材料分别进行比例和非比例应力循环加载棘轮效应试验， 揭示了两种不锈钢材料的棘轮效应的一些特征， 和导致这些棘轮效应特征的原因， 得到了一些有意义的结果。
The ratchetting experiments of 316L and 1Cr18Ni9Ti stainless steel cyclically loaded under proportional and nonproportional conditions were performed respectively.It illustrated that how the stress amplitute,mean stress and the histories of them influencing ratchetting,The evolution features of ratchetting and conducting factors were investigated.Some significant results which seek to be contributions to the model of ratchetting were obtained.
