摘要
Abstract
Both the serrated yielding of materials and singularity of the strain path in low strain level would cause discreteness of plastic stain ratio r value,and it would be hard to accurately evaluate the property of materials. The interval r value was a good solution for this problem due to its unique advantage of the result reproducibility. During the calculation of interval r value,whether or not theεb-εL regression line passed through the origin point of the coordinate would lead to the difference in results,but the difference was not obvious in most condition.Whether or not the boundary condition of interval r value calculation should be set hadn’t been confirmed as far as the reproducibility.关键词
