Experimental and numerical investigation on heavy-caliber shaped-charge penetration in thick concrete target

The independent developed software EXPLOSION-2D was adopted to simulate the heavy-caliber shaped-charge forming, and the laws of heavy-caliber shaped-charge forming were obtained and the influence of blasting height for shaped charge penetration thickness concrete target was simulated. Based on the performance parameters of the penetrators, two kinds of shaped-charge structures which had good penetration effect were selected to penetrate in the thick concrete target. According to the simulation results the best shaped-charge structure which could penetrate the thick concrete target well was designed and the corresponding experiments were carried out. The concrete target after the experiment was cut to evaluate the concrete target damage in different location by the inside damage of concrete target and the hole diameters of different location were measured. The test conditions were simulated by the EXPLOSION-2D software and the simulation results was compared with the experimental results. The comparison results show that the numerical simulation technology can evaluate the damage of concrete target effectively.
