This paper has studied the changes about tensile strainhardeningexponent (n-value) in three kinds of st steels by testing n-values and found changing tendency of them.
进行三种ST钢的应变硬化指数n值试验，分析试验结果，研究n值在整个应变区间的变化趋势。

The load point displacement caused by single load for two dimentional cracked body with certain strainhardeningexponent is divided into its linear-elastic and plastic components.
将具有一定应变硬地指数的二维裂纹体在单一载荷作用处的位移分成线弹性部分和塑性部分。

Compared with the strip produced by conventional austenite rolling, the yield strength of the ferrite rolled strip was lower by about 20%, with same elongation and strainhardeningexponent.
