对Mises屈服条件的塑性轴对称变形方程的研究

A Study of the Equation of the Symmetric Deformation of Plastic Axis on Mises Yield Conditio n

用Ｍｉｓｅｓ屈服条件，研究了理想刚塑性材料的轴对称变形方程，证明了平衡方程和速度方程都是双曲线型的，并且它们的特征线都和滑移线重合，因此可构造特征线场进行求解。

This article studies the equation of axially symmetric deformation of an ideal rigid一plastic material on Mises Yield Condition It tries to prove that the equations of equilibrium and velocity are both hyperbolic,and moreover their characteristic lines and slip-lines coincide.
