The interest regarding use of aluminium alloys in lightweight protective structures is today
increasing. Even so, the number of experimental and computational investigations giving
detailed information on such problems is still rather limited. In this paper, perforation
experiments have been performed on AA5083-H116 aluminium plates with thicknesses
varying between 15 and 30mm impacted by 20mm diameter, 98mm long, HRC 53 conical-
nose hardened steel projectiles. In all tests, initial and residual velocities of the projectile …

The use of aluminium alloys in lightweight protective structures is increasing. Even so, the
number of experimental and computational investigations that give detailed information on
such problems is limited. In an earlier paper by some of the authors, perforation experiments
were performed with 15–30mm thick AA5083-H116 aluminium plates and 20mm diameter,
98mm long, HRC 53 conical-nose hardened steel projectiles. In all tests, initial and residual
velocities of the projectile were measured and the ballistic limit velocity of each target plate …
