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.

When using multiple mics, though, slip the track for any mic set at some distance from the head so that its phase lines up with the dynamic mic inside the kick.

This is confirmed by the investigation of the surface slip lines of deformed samples, dislocation configuration and antiphase boundaries of dislocation move trace.
