Numerical Study on the Equivalent Target for Deep Penetration

Abstract:

The influence of radial and axial boundary effect on penetration effect are calculated, numerical simulation are executed to compute the kinetic projectile against deep hard target by finite element code, the boundary effects were achieved for different velocity range. Result shows that the minimal D_t/D_p (diameter ratio of target to projectile) for impact velocity 600m/s is 17.5, while the minimal D_t/D_p for impact velocity 900m/s is 20. Furthermore, the depth of equivalent target to substitute semi-infinite target is twice of penetration depth limit for impact velocity 300m/s, and 1.6 times respectively, for impact velocity 600m/s, 900m/s.
