This article deals with the evaluation of the ballistic resistance of aluminum plates subjected to high velocity impact by a rigid cylindrical projectile. Important impact variables such as the ballistic limit, the ballistic energy and the impact load time history are predicted using the ANSYS LS-DYNA software. A comparison with the ballistic resistance of GLARE 4A fiber-metal laminated plates is also implemented. The time history of the transient impact load of the collision on the aluminum targets is analyzed and useful conclusions are drawn. It is found that the ballistic limit and the ballistic energy of aluminum and GLARE 4A panels increase as their thickness and their areal weight become higher. It is also found that 2024-T3 aluminum plates offer comparable ballistic limit velocities with the GLARE 4A fiber-metal laminates of the same thickness or the same areal weight.
