An explosively formed penetrator (EFP), also known as an explosively formed projectile, a self-forging warhead, or a self-forging fragment, is a special type of shaped charge designed to penetrate armor effectively, from a much greater standoff range than standard shaped charges, which are more limited by standoff distance.

Sep 21, 2023 · Explosively formed penetrators (or projectiles), better known as EFPs, were responsible for wounding and killing many American military personnel throughout the War on Terror, quickly earning...

Jun 1, 2014 · In this paper, EFP with fins formed by three-point initiation was designed to study the whole process of its formation and flying characteristics. The formation process of EFP with fins was analyzed by LS-DYNA and the aeroballistic study was conducted through experiment.

Jan 1, 2019 · The EFP slug was assigned an initial velocity of 1200 m/s based on the results of motion analysis of the high-speed video recordings of the flying EFPs from the field explosive trials.

Jun 12, 2017 · Explosively formed penetrator (EFP) warheads have been designed to project a single massive high velocity penetrator to attack the top of armored vehicles.

Nov 2, 2019 · Improvised explosive devices (IEDs) have proven to be highly lethal tools frequently used in asymmetric warfare. This has been particularly true of explosively formed penetrator (EFP)-based IEDs.

The formed slug of the EFP is ≈45 g and has a velocity of around 2500 m/sec. EFP detonation and slug forging are numerically simulated using an LS-DYNA3D finite-element code to optimize the design parameters of the EFP.

Nov 21, 2005 · The formed slug of the EFP is about 45 g and has a velocity of around 2500 m/sec. Penetration of the slug is expected to detonate or deflagrate the equivalent TBM warhead, so a one-shot EFP is used as a projectile to eliminate the need to protect the launcher against oncoming explosion prod-ucts.

EFP - Explosively Formed Penetrator An EFP, or Explosively Formed Penetrator, is a shaped charge formed by explosively shaping a metal plate or liner into a slug or rod shape and accelerate it towards a target.

Jun 11, 2018 · EFPs are self-forging warheads designed to effectively penetrate armor and fire in a way similar to cannons. When fired, the explosive charge deforms a concave metal plate into a slug or rod shape. The shape forms as the plate accelerates toward an intended target. EFPs can breach tank armor 300 feet away.
