Abstract
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.
Highlights
As an effective anti-ship weapon, semi-armorpiercing warhead has attained important application in military [1]
It can be concluded that incidence angles have no remarkable influence on penetration capability of the projectile under the circumstance of zero attack angles, which are mainly contributed by varying in penetration process which increases with the incidence angle
When the attack angle is larger than 5o, adiabatic plugging damage mode is exhibited with different size of plugs formed in all other instances, which could be contributed by interaction of compression wave and dilatational wave at the back of the target
Summary
As an effective anti-ship weapon, semi-armorpiercing warhead has attained important application in military [1]. In this paper FEM models of semi-armor-piercing warhead penetrating aircraft carrier deck are established, which are validated by related experimental data. The process of semi-armor-piercing warhead penetrating aircraft carrier deck with different incidence angles and attack angles are carried out. 2.1 Grid Model A half grid model of the projectile and the target are established as Fig. and Fig. showed. The projectile is made up of shell, charge and fuze, which is 16kg in weight, 370mm in length, and 105mm in diameter. The simplified grid model of the target about “Nimitz-class” aircraft carrier with deck thickness of 50mm is created according to the literature [1]. A nonrefection boundary condition is defined to simulate large extent in length
