Numerical Simulation of High Performance Shaped Charge Penetrating Concrete Targets

Tandem warhead systems consist of a precursor shaped charge and a following kinetic energy projectile containing high explosive filling. This paper presents a numerical simulation analysis of the penetration forming and the process in which the shaped charge penetrated into concrete targets by using AUTODYN software. The shaped charge is consist of different materials, different standoff, different liner curvature and thickness. Parameters for the liner structure which can detemine ideal aperture and penetration depth are acquired. The simulation results are in agreement with them of the experiment.
