Numerical simulations of semi-armor-piercing warhead penetrating aircraft carrier target

FEM models of semi-armor-piercing warhead penetrating aircraft carrier deck are established, which are validated by related experimental data. Base on the models, the process of semi-armor-piercing warhead penetrating aircraft carrier deck with different incidence angles and attack angles are carried out. The results show that incidence angles have no remarkable influence on penetration capability of the projectile under the circumstance of zero attack angle. Ductility reaming damage mode and adiabatic plugging damage mode are exhibited in the penetration process. Attack angles have notable influence on penetration capability of the projectile. The FEM models and the results could provide reference for penetration effect research of semi-armor-piercing warhead penetrating aircraft carrier target.
