By modifying the EPIC-2 hydro-code one can calculate the loading history of an impacting projectile on a target. Loading histories of 20 mm projectiles for impact velocities of 366 ms, 1012 ms and 1508 ms on 914 x 914 mm rolled homogeneous armor plates were calculated with this code. These histories were used in ADINA finite element analyses of the plates. Comparisons of the measured and the calculated plate responses show that hydro-code generated loading histories can be used in finite element analyses of nonperforating ballistic impact.
