Abstract

Performance improvement and increasing of penetration of Explosively Formed Penetrators (EFP) is one of the most considerable issues in the field of defense researches. There are various solutions to achieve this purpose, including innovative designs in the field of charge, linear, skin, Explosive Train, etc. In this paper, the effect of Multi-Point Initiation on the formation and penetration of EFPs is investigated using by finite element method and LS-Dyna Code. Furthermore, the simulated model was developed and exprimental tests were performed to measure the penetration depth and hole diameter caused by the impact of EFP to the target of steel plate. Comparison of simulations and experimental results shows good agreement. Also measurements shows the 40% increase of penetration depth in case of Multi-Point Initiation in comparison with single initiation, which can be good result in performance improvement of EFP Warhead.
