โœฆ Synopsis

We investigated the penetration capabilities of segmented penetrators consisting of small aspect ratio segments, (l/8 I L/D 5 1) using axisymmetric numerical simulations for constant mass, diameter, and collapsed length, tungsten alloy, long-rod penetrators impacting semi-infinite thick rolled homogeneous armor steel (RHA) at 2.6 km/s. The specific technical issues investigated were whether the total penetration of multiple segments is a constant multiple of the penetration of a single segment (not necessarily the first segment); whether the primary cause of any penetration degradation was due to entrance effects or to material remaining at the crater bottom; and whether the cumulative degradation effects for multiple segment impacts changed the optimum aspect ratio based upon single segment penetration.

The penetration ability of asymmetric long-rod projectiles at 2.6 km/s is investigated in this numerical study. Five different projectile cross sections were considered. Results from the simulations indicate that the penetration velocity of the projectiles is only marginally influenced by the cross-

This paper presents the results of scale size experiments using a tungsten-alloy long-rod projectile fired against 97.5% Al 2 O 3 ceramic targets at 1.8 and 2.6 km/s. Two targets were used, one having lateral steel confinement; the other without. The projectile overmatched the target, and residual p

Forty terminal ballistics experiments were performed to measure the penetration of simple confined boron carbide targets by long tungsten rods. Impact velocities ranged from 1.5 to about 5.0km/s. The experiments were performed in the reverse ballistic mode using a two-stage light-gas gun. For tests

A 51 mm thick plate of high-strength low-alloy (HSLA-100) steel was impacted by 6.4 mm diameter tungsten carbide spheres traveling at velocities ranging from 0.8-2.5 km/s. The width and depth of the crater for each impact event are provided in tabulated form and graphed as a function of velocity. Th
