This paper introduces a new way for defining the maximum principal strain direction in planestraincondition.
本文介绍了一种确定平面应变中最大主应变方向的新方法。

Under planestraincondition, the strain localization starts around the peak stress state; and a V-shaped shear band is formed at the residual stress state.
在平面应变压缩条件下,砂土在峰值应力状态附近出现应变局部化现象,在残余状态最终形成一条V型剪切带。

Furthermore, from the analytical results indicate that the shear band mode of discontinuous bifurcation is essentially identical with slip line in the planestraincondition.
