Adiabatic Blanking: Influence of Clearance, Impact Energy, and Velocity on the Blanked Surface

Journal of Manufacturing and Materials Processing, 2021
In contrast to other cutting processes, adiabatic blanking typically features high blanking velocities (>3 m/s), which can lead to the formation of adiabatic shear bands in the blanking surface.

On what controls the spacing of spontaneous adiabatic shear bands in collapsing thick-walled cylinders

EPJ Web of Conferences, 2015
Shear bands formation in collapsing thick walled cylinders occurs in a spontaneous manner. The advantage of examining spontaneous, as opposed to forced shear localization, is that it highlights the inherent susceptibility of the material to adiabatic ...

Dynamic failure of viscoplastic structures under ASB and micro-voiding

EPJ Web of Conferences, 2018
Adiabatic shear bands are known to cause premature structural failure in high strength metals and alloys. The observation of adiabatic shear bands inside partially fractured specimens evidences the presence of micro-voids as the precursor of the ultimate
