Abstract

The efficiency of segmented rods penetrating into semi-infinite steel targets was investigated numerically by hydrocode simulations with impact velocities varying between 2000 and 5000 m/s. In a second phase segmented elements were integrated in experimental projectiles and these projectiles were accelerated by means of a powder gun to verify the launchability of such projectiles and to confirm the results of the numerical simulations. As predicted by the numerical simulations, we observe an increase of the penetration depth in the order of 10% with a 4 segments spaced projectile, in the case of an impact velocity of 2100 m/s.
