Abstract
We present an empirical relation for the penetration depths of rigid spheres impacting metallic targets at ordnance velocities. This relation was derived through 2D numerical simulations for various sphere/target pairs, that followed their penetration depths in terms of the impact velocity, the sphere/target density ratio, and the dynamic strength of the target. The numerically derived empirical relation is shown to account for test data from several publications.
