An adiabatic shear band formed along the main shear stress around the penetrated hole is approximately consistent with the direction of plastic deformation slip lines in static state.
弹孔周围的绝热剪切带沿主剪应力方向形成，与静态塑性变形滑移线方向接近，绝热剪切带上不均匀的变形将产生微裂纹和微孔洞。
The reason for the sawtooth chips is that the adiabatic shear localization occurs in the primary deformation zones when thermal softening exceeds strain and strain rate hardening.
锯齿形切屑产生的原因是第一变形区内因热软化超过应变和应变率强化而发生了绝热剪切局部化。
