在室温下对３０４不锈钢在非比例循环加载下的棘轮行为进行了实验研究在圆形、菱形和直线形状的非比例双轴循环加载路径下，研究不同轴向平均应力、等效应力幅值大小及其历史下材料的棘轮行为特征．为了比较，还进行了单轴加载下该材料的循环棘轮行为实验．实验表明，３０４不锈钢的室温非比例循环棘轮行为明显地依赖于加载路径的形状；与单轴循环棘轮行为一样，非比例循环棘轮行为也明显地依赖于轴向平均应力和等效应力幅值的大小及其历史．
The ratcheting behavior of 304 stainless steel under non-proportional cyclic loading was investigated at room temperature. Under non-proportional biaxial cyclic loading paths of circular, rhombic and straight shapes, the effects of different axial average stresses and equivalent stress amplitude And its history of ratcheting behavior of materials. For comparison, a cyclic ratcheting behavior of the material under uniaxial loading was also performed. Experiments have shown that the non-proportional circulating ratcheting behavior at room temperature of 304 stainless steel significantly depends on the shape of the loading path. As with the uniaxial ratcheting behavior, the non-proportional circulating ratcheting behavior also significantly depends on the axial mean stress and equivalent stress amplitude Size and history.
