Simulation of penetration in normal strength concrete for a projectile with L/D=9

The performance of penetrating warheads has increased the last few years by introducing penetrators with a length to diameter ratio of almost 10. This requires new designs to prevent penetration of future protective structures.Penetration of concrete targets is studied by the use of numerical simulation. The diameter of the used model penetrators is 50 mm, and the length to diameter ratio is 9 for the projectiles. Comparisons are also made with reinforced and unreinforced concrete targets constructed of normal strength concrete. The nominal impact velocities for these reference tests are 420 and 460 m/s.
