initial shear stress

基本解释

The stress-stain curve shows the strain-hardening characteristic without initial shear stress.
当不存在初始剪应力时，应力–应变关系表现为硬化型曲线；
The strength resisting liquefaction increases along with the increase of consolidation pressure, sample density initial shear stress, but the increase of initial shear stress is limited.
抗液化强度随固结压力、试样密度、初始剪应力的增加而增加，但初始剪应力的增加量是有一定限度的。
If the initial shear stress is close to the peak shear stress, a relatively high velocity of pore water pressure is generated at the beginning of rotation, but later pore water pressure decreases.
若初始剪应力接近峰值剪应力，主应力轴开始旋转时的孔压上升速率相对较高，但后期孔压反而会下降；

初始剪应力
Thus the initial shear stress that the role can not be ignored.
因此认为初始剪应力的作用不容忽视。
