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 …

Improving the final EFP shape and especially the solidity (i.e. the ratio of solid volume to the volume determined from the maximum dimensions) of the EFP usually involves lower …

Jul 1, 2016 · Ballistic parameters, such as geometry, type of detonation (number and position of detonators) and materials, influence the stable flight velocity of the EFP and, consequently, its …

Jun 1, 2014 · Explosively formed penetrators (EFPs) have been used in a number of munition systems to defeat armor, masonry and concrete targets. EFPs are launched from considerable …

Jan 15, 2018 · Subjected to high velocity impact of explosively formed projectile (EFP) which is a kind of easy-deformable and soft projectile, the ballistic performance of monolithic and …

Explosively Formed Projectile (EFP) is formed by high explosives, which has high speed with good pneumatic shape. Compared with the jet, EFP has larger mass and diameter, so that it …

Jan 1, 2013 · For this purpose, a modular soft-recovery apparatus was designed to non-destructively recover the Ta-2.5W explosively formed projectile (EFP) in the ballistic endpoint.

Apr 8, 2019 · The results suggested that after an EFP passed through an ERA, its RDOP to target decreased with an increase in the angle and explosive layer thickness. The higher the density …

Jan 1, 2011 · This chapter is designed to provide the reader with a basic guide to the historical context, physics, and terminal ballistics involved in HEAT and EFP weapon systems. Table 8.1 …

Based on the Johnson–Cook constitutive model parameters and the special conditions in the forming phase of EFP, the critical velocity gradient Δvcr Δ v cr can be determined by …
