Abstract

Numerical simulations by LS-DYNA were carried out to study the influence of MEFP space, explosive charges and radius of curvature on the damage efficiency of MEFP. While the MEFP space ranges from 2.5mm to 12mm, the tail, length and head velocity of the formed EFPs decrease as the MEFP space increases, the flight stability of MEFP reduces; As for different explosive charge, the tail, length and head velocity of the formed EFPs increase as the explosive vary from TNT to B explosive, the flight stability of MEFP is enhanced; As for different radius of curvature, the tail and head velocity of the formed EFPs increase as radius of curvature increases except for the length of the EFPs, the flight stability of MEFP is improved. The results provide a reference for MEFP design.

Key words： MEFP; MEFP space; different explosive charge; radius of curvature
