N2 - The jet formation and penetration behaviors of shaped charge with a reactive material double-layered liner (RM-DLL) are presented in this paper based on the AUTODYN-2D code. Numerical results show that the wall thickness ratio of the RM-liner to the metal liner has a significant influence on the formation and penetration characteristics of composite jet. As the wall thickness ratio increases, the tip velocity of composite jet, the pressure on the RM-liner, and the temperature of RM-elements decrease. The effect of the wall thickness ratio on the penetration performance of RM-DLL shaped charges against steel targets significantly depends on the RM-initiation delay time (τ). The penetration depth (PD) of the composite jet with titanium liner into the steel target is limited. In the case of the RM-tungsten liner, the RM-mass following into the penetration crater is very small. In the case of the RM-copper liner, the penetration capability of composite jet is well matched with the mass of follow-thru RMs. Compared with the PD, the standoff has a more significant impact on the RM-mass entering the penetration hole.
