Abstract

Abstract: A new integral multiexplosively formed penetrator (MEFP) warhead is designed in order to improve the hit probability of explosively formed penetrator (EFP). The feasibility of the warhead structure is verified in static blast experiment. And the processes of MEFP forming and penetrating a target are simulated using LSDYNA3D. The simulated results coincide well with the experimented data．The result indicates that such a warhead can form seven explosively formed projectiles which have a definite mass and direction and can penetrate a 15mmthick 45#steel target, thereby increasing effectively the number of damage elements and damage area.

Key words: ordnance science and technology, multiexplosively formed penetrator, penetration, numerical simulation
