Abstract

Experiments for penetration into concrete by shaped charges with different liner materials, different cone angles, different liner thicknesses at different standoffs were performed in this paper. The influences of liner material, cone angle, liner thickness and standoff on crater diameter, hole diameter, crater depth and penetration depth were analyzed. Resistance of concrete target was calculated using the cavity expansion theory; penetration depth and hole diameter were predicted using the modified Bernoulli's equation and two-phase cavity expansion theory, and the theoretical results are consistent with the experimental ones. The formation processes of 57 different shaped charge penetrators with AUTODYN software were simulated, and the penetration processes into concrete for several typical shaped charge penetrators were also simulated. The simulation results of hole diameter and penetration depth are in good agreement with the experimental ones. Mechanism of crater formation under the action of shaped charge was investigated, which indicates that the mechanism of crater formation for aluminum liner is different from that for steel and copper liner.
