Coulomb材料中滑移线性质的研究

The Study of Slip Line's Nature in Coulomb Material

对Ｃｏｕｌｏｍｂ材料中滑移线的性质进行了研究，结论是沿β（α）滑移线移动，则α（β）滑移线曲率半径的变化等于沿β（α）线滑移的距离与ｃｏｓφ的乘积．

The slip line's nature in coulomb material is studied. The conclusion is that the changing value of α (or β) slip line's curvature radius is equal to along β(or α) slip line's shifting distance multiplied by cosφ if along the β (or α) slip line shifted, which extend Hencky's second law's applied scope from Tresca material to Coulomb material.
