摘　　要：导出了单轴拉伸试件的等效应力σｉ与等效应变ｅｉ间的关系．按照弹塑性理论中关于应变硬化模量ＥＴ的定义，给出了由σｉ～ｅｉ曲线计算ＥＴ的插值方法．文中列出了一组典型实测与计算数据，以供参数．The relation between the effective stress and the effective strain about the uniaxial tensile test was intraduced. According to the definition of the strain hardening modulus, the interpolation to calculate the strain hardening modulus from the effective stress effective strain curve was given. A group of experimental and calculated data were gived.
