Shaped charge with multiple liner structure was designed to improve the depth of EFP penetrate armored steel target. The numerical simulation of forming of EFP warhead and the process of penetrating armored steel for 5 shaped charge structures was carried out by ANSYS/LS-DYNA software. Explosive energy utilization rate and depth penetration ability with different layers liner were analyzed. The results show that the coaxial series EFP can be formed by laminating multiple layer hemispherical liners with the same material. Compared with the single-layer structure, the multi-layer structure can deliver higher energy utilization and greater penetration ability. The depth penetrated by 3 and 5 series EFP was increased by 63.4%.
