Abstract

When the new-style flat-nose projectile impacts the two-laminated target composed of the concrete and the soil at a certain velocity, the great inertia force produced by the high deceleration will make worse effect on the structural strength of the projectile shell and its internal components. By using the three-dimensional LS-Dyna finite element software, the penetration of the flat-nose projectile into the concrete and soil target at different velocity was simulated. The phenomena of the concrete damage were in agreement with the experimental results. The penetration performance of the flat-nose projectile was discussed. As for the flat-nose projectile with the diameter of 69mm and the mass of 1.8kg, the penetration deceleration will reach 38640~48300g at the impact velocity about 77~96m/s.
