摘要

The penetration and damage effects of reactive material jet on concrete target are studied through experiment and simulation. The typical damage pattern of concrete target subjected to reactive jet was obtained, and the influences of formulation and stand-off distance on damage effect were studied. The experimental results show that the reactive jet produces a large conical crater and a crack zone in concrete target. The reactive liner with more gaseous products induce more violent damage on the concrete target. The produced crater diameter is over 10 times of the shaped charge diameter at a stand-off distance of 1.0D. Based on the AUTODYN-3D platform, the reactive jet against concrete target is numerically simulated to reveal the influence mechanism of the stand-off distance on the damage effect. With the increase in stand-off distance, the amount of reactive material penetrating into the crater trajectory decreases, and the penetration depth increases firstly and then decreases. The kinetic penetration time and the reaction delay time of reactive materials match well at the stand-off distance of 1.0D.
