Abstract

Abstract

Multiple explosively formed projectile (MEFP) can effectively raise the utilization rate of explosive and the hit rate. The forming process of groove type MEFP and the process of penetrating double nonseptate steel target based on LS-DYNA are studied. The results show that the forming process of groove type MEFP should pass through five stages: overturn, the head extrusion fracture, the rear tensile fracture, cross flying and stable flying. The cross flying is caused by the radial force which comes from detonation wave. Penetration process should pass through three stages: Spud in, united penetration and breakthrough stage. The simulated results are consistent with the experimental results.
