Abstract: To improve the damage ability of integral multiple explosively formed projectiles(MEFP), the formation process of integral MEFP formation with different materials of charge was studied using LS-DYNA code,and the feasibility of the warhead with B explosive is verified in static blast experiment. The simulated results coincide well with the experimented data. The results indicate that with the increase of density, detonation velocity, pressure of charge, and the velocity and length-diameter ratio of the central projectile increases significantly and the penetration performance enhances. The shape of surrounding projectile changes from ball to rod gradually,and the flight stability of projectile decreases. Therefore, selecting suitable explosive charge could improve the damage effect based on particular aim.
