根据Mises屈服条件,基于球应力分量对塑性变形无作用的前提,本文导出了恒延伸轧制变形区出口处剪应力τ的计算公式,并找出了恒延伸轧制变形区出口处τ沿轧件厚度方向上的分布规律。 According to the Mises yield condition, based on the premise that the ball stress component has no effect on the plastic deformation, the formula for calculating the shear stress τ at the exit of the constant elongation rolling deformation zone is deduced and the τ rolling at the exit of the constant elongation rolling deformation zone is found out The distribution of the thickness direction of the law.
