Study on formation characteristics of the shaped charge with an untypical reactive material composite liner

Abstract

The shaped charge with reactive material composite liner could not only has good penetration capability, but also has a strong internal explosion damage effect. The influence of the ratio of reactive material liner thickness, the ratio of reactive material liner height and the cone angle of composite liner on the forming characteristics of the untypical reactive material composite jet was studied by using the finite element software AUTODYN. The numerical simulations show that with the increases of the ratio of reactive material liner thickness and the ratio of reactive material liner height, the head velocity of the composite jet increases, but the distribution of titanium in the jet becomes unfavorable for penetration. With the increase of the composite liner cone angle, the diameter of the composite jet increases, but the head velocity of jet decreases.
