The response of aluminium plates (6061-T6) under low velocity impact is investigated numerically using ABAQUS software package. Firstly, the effect of the sample thickness on the perforation resistance of the aluminium plates is undertaken. It was shown that the perforation behaviour of the plates investigated increases with the target thickness and the maximum resistance to perforation, for the range of thicknesses investigated, was achieved using 4 mm thick panels. In order to capture the influence of the projectile shapes on the perforation behaviour, the aluminium plates were impacted with different head shapes impactors. The results showed that plates impacted with a flatted impactor offer the highest perforation resistance. Moreover, the results showed that changing the size of the targets has no significant change on the dynamic behaviour of the plates investigated in this study. Finally, it is suggested that the finite element models developed in this study can be used to capture the effect of the geometric and loading conditions of aluminium plates under perforation by low velocity impact.
