“…Generally, an explosively formed projectile system consists of charge, liner, casing and wave-shaper. The geometric and physical parameters like length, diameter, liner shape and material and type of charge strongly influence the shape and velocity of the penetrator [1].…”

“…Figure 1. The schematic of EFP configuration [1] Similar to shaped charge (cumulative) projectiles, after detonation, very high pressure collapses the liner into the appropriate shape (depending on the design) of the penetrator moving at a speed of up to 3 km/s [2]. The process of penetrator formation from the initial shape of the liner is shown in Figure 2 [3].…”

Explosively formed projectile (EFP) is a self-forging shape charged structure having very high penetration ability compared to conventional kinetic energy projectile. The penetration capability of an EFP is strongly dependent on various design parameters. The main parameters can be roughly divided into geometric and material parameters used in the warhead configuration. The present research is an effort to study the effect of metal casing thickness, type of metal used for casing, explosive type, liner thickness, type and configuration on the formation of EFP. Effectivness of an EFP is studied in terms of final velocity and shape of formed penetrator. The study is carried out by performing a number of simulations by using explicit finite element (FE) hydrocode ANSYS/Autodyn.
