Analysis of the Perforation of Monolithic and Simple Laminate Aluminum Targets as a Test of Analytical Deformation Models
Abstract
Several models are used to estimate the ballistic limit velocities of homogeneous aluminium targets impacted by small calibre armour piercing projectiles and blunt fragment simulators. It is demonstrated that a careful use of the models, combined with an understanding of material failure mechanisms, enables good estimates of ballistic resistance to be made using the analytical techniques. One of the techniques is modified and adapted to the calibration of ballistic resistance of simple two plate aluminium laminates. Correlation of computations with empirical data demonstrates that the technique is a useful design tool in predicting the optimum relative thicknesses of thw two plates and the laminate performance. Keywords: Aluminium, Models, Laminates, Terminal ballistics, Armor piercing ammunition, Armor, Failure mechanisms, Fragments, Penetration and Australia.
