Abstract: A new type tandem shaped charge warhead, which produces a high-velocity jet and low-velocity jetting projectiles, was proposed based on the characteristics of a reinforce concrete target. The formation processes of the prepositioned charge and rear-mounted charge were simulated by the three-dimensional finite element dynamic code LS-DYNA3D. Series static armor-piercing tests were carried out to validate the performance of the proposed tandem shaped charge and in the experiment it penetrated a reinforce concrete target and a 45 steel target. Experimental results reveal that the proposed tandem shaped charge can do more damage to reinforce concrete target and drill a larger hole in it than the conventional tandem shaped charge. Experimental and simulated researches show that the new tandem shaped charge has promising applications to the tandem shaped charge warheads against hard objects such as reinforce concrete targets, airdrome runways, multi-plate spaced targets.
