This work deals with several issues related to the deep penetration of spherically nosed rigid projectiles impacting metallic targets at normal incidence. The most important issues in these processes are the constant resisting stress acting on the pr

A large number of 3D numerical simulations were performed in order to follow the trajectory changes of rigid CRH3 ogive-nosed projectiles, impacting semi-infinite metallic targets at various obliquities. These trajectory changes are shown to be relat

We reanalyze the results from a set of terminal ballistics tests in which large limestone targets were impacted by similarly shaped rigid projectiles having different sizes. Our first goal is to show that the data in terms of penetration depths as a

The purpose of this Comment is to highlight several inaccuracies in the recently published paper of Yankelevsky and Feldgun, which criticizes our work on concrete penetration. The main subject of their criticism concerns our treatment of the entrance

The work presented in this paper addresses the issue of determining the appropriate values for the dynamic strength of metallic plates perforated by rigid sharp-nosed projectiles. This issue is especially important for materials which exhibit strain

The aim of this work is to demonstrate that one can derive the value of the dynamic resistive stress, which a given target exerts on a rigid projectile, by following the force needed to push a rigid indenter into the target in a static deep indentati

The ability to simulate shear bands evolution in thick-walled-cylinder (TWC) experiments is required to understand their spontaneous formation and propagation. Recently we presented experiments on electro-magnetically collapsing metallic cylinders (L

The effect of friction on the shanks of rigid projectiles penetrating concrete targets is still an unresolved issue for the terminal-ballistics community. In the present note we argue that this retarding force on the shanks of rigid projectiles can b

The penetration of rigid projectiles in polycarbonate (PC) targets is explored through deep indentation tests with conical-nosed indenters and ballistic penetration results for armor piercing 7.62 mm projectiles. We found that the resistance to penet

The diameter of holes and craters in metallic plates impacted by hypervelocity projectiles is investigated through a series of numerical simulations. We first compare the simulations results with an analytical model for the crater diameter in a semi-
