N2 - Double layer shaped charges (DLSC) are special type of shaped charges which have recently attracted the attention of some researchers. In this paper, the application of overdriven detonation (ODD) in the design of DLSC is analyzed. The previously reported experiments carried out for comparison of the ballistic performance of DLSC with the ordinary shaped charge (OSC) are simulated using the hydrodynamic software LS-DYNA. The numerical simulations reveal that the use of concentric layers of the charges is not as efficient as supposed, to improve the performance of shaped charges. It was found that OSC may have some advantages over DLSC, especially at smaller lengths. It was also found that the shaped charges in which an explosive with higher Chapman-Jouguet pressure is utilized in the inner core, yield more penetration. The reported experimental results also support the numerical simulations presented.
