tensile strain hardening exponent的意思|示意

This paper has studied the changes about tensile strain hardening exponent (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。

Yield strength and ultimate tensile strength, work hardening exponent and normal anisotropy of plastic strain ratio decrease but planner anisotropy of plastic strain ratio increases.

屈服强度、抗拉强度、加工硬化指数和塑性应变比厚向各向异性降低，塑性应变比平面各向异性增大；
