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
