Abstract
The formation of linear explosion formed penetrator(LEFP) from linear shaped charge detonated from one end point was studied both theoretically and experimentally, and a numerical simulation was also carried out. By decomposing the detonation velocity vector into spherical and slide components, the theoretical model described the tip velocity change of LEFP. The numerical model illustrated the formation of LEFP and the tip velocity agreed with the theoretical model. The validation of the theoretical and numerical models was verified by experiment, in which steel targets were used to show the effect of LEFP. The results showed that average tip velocity was 2658.4 m/s at 100 mm to the charge mouth. The theoretical and numerical velocity values and distribution curve were very close to the experimental ones. This work may further develop the theory of LEFP and linear shaped charge.
