Charge Structure

In order to obtain a linear explosively formed projectile (LEFP) with a good flying form under large stand-off, the LS-Dyna finite element analysis software and arbitrary Lagrangian - Eulerian (ALE) algorithm were used to simulate the forming process of LEFP with a 30mm charge structure diameter. On the basis of that, the only changed factor was the curvature radius of the liner which was selected as 0.65D, 0.75D, 0.85D, 1.0D and 1.1D for the simulation of LEFP forming progress. The warhead speed-time curves and fracture surfaces of the LEFP are analyzed, with liner radius decreasing, the projectiles become more slender, and instead, the larger radius liner forms flat and wide LEFP. Slender LEFP is conductive to penetration, however the over small radius which cause the reduction of weight and kinetic energy makes fracture easily, oversize radius influence either end of LEFP that warps upward seriously , what means speed grads of both ends differ greatly .The suitable radius ranges from 0.75D to 1.0D.
