在室温下对304不锈钢进行了多种长短轴比的椭圆形、菱形等非比例循环加载路径下的应力与应变路径形状、路径的应力与应变幅值、平均应变及其加载历史的影响的系统实验.结果表明,材料的循环塑性行为强烈地依赖于应力与应变路径形状、路径的应力与应变幅值及其加载历史.
The system of stress and strain path shape, path stress and strain amplitude, average strain and loading history of 304 stainless steel under various non-proportional cyclic loading paths such as oval and diamond at room temperature The experimental results show that the cyclic plastic behavior of materials depends strongly on the shape of stress and strain paths, the stress and strain amplitude of paths and their loading history.
