Abstract

 Many analytical models have been already presented for PENETRATION analysis of TARGET="_blank"> LONG ROD TARGET="_blank"> PROJECTILEs. In most of these models, for a specific TARGET="_blank"> PROJECTILE, TARGET and impact specifications, only unknown parameter (the depth of PENETRATION) is computed. In this paper, the formulation of Alekseevskii-Tate analytical model has been modified to be able to evaluate and design the TARGET="_blank"> PROJECTILE specifications, for a desired PENETRATION depth. Also by additional relations for kinetic energy and no BUCKLING conditions of TARGET="_blank"> PROJECTILE, a new algorithm is presented. In this method, by solving the resulted equations, the TARGET="_blank"> PROJECTILE specifications, including impact velocity, initial length, diameter and mass, is determined for a known PENETRATION depth into the TARGET. Comparison of the results of these formulations with other experimental works and numerical solutions by AUTODYN shows good agreement. Finally, as an applicable example, terminal ballistic design of a rod TARGET="_blank"> PROJECTILE is done, and TARGET="_blank"> PROJECTILE specifications are presented.
