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.
The adiabatic shearing phenomena were often found in metallic materials under high-strain, high-strain-rate deformation.

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.
