Jet Forming Characteristics of Shaped Charge with Reactive Material Composite Liner

Abstract

The influence of metal liner material, the ratio of inner and outer liner diameter, and the cone angle of composite liner on the forming characteristics of the reactive composite jet were studied by using the finite element software AUTODYN. The numerical simulations show that with the increase of the inner liner diameter, the tip velocity of the composite jet decreases, and the following situation of the reactive material becomes worse. With the increase of the cone angle of the composite liner, the continuity of the composite jet becomes better, but the jet tip velocity decreases. With the increase of the material density of the metal liner, the velocity of the composite jet tip decreases, but the continuity of the jet becomes better.
