We studied an optional/dual-mode warhead with an ejectable cross-shaped cutting reseau fixed at a proper place before the liner to realize multi-function of ammunition based on 60 mm arc-cone liner Explosive Formed Projectile (EFP) charge configuration. The optional/dual-mode warhead can change the kill elements mode according to the target properties (heavily or lightly armored targets), and can form single EFP or MEFP (Multiple Explosively Formed Projectile) to provide the most effective attack. The whole process of formation, flying and penetration of single EFP and MEFP was simulated using LS-DYNA3D. The simulation results are in good agreement with the experimental data. This study indicates that the single EFP has a good aerodynamic stability at a velocity of 1 508 m/s and it can penetrate through the 45 steel targets with a thickness of 30 mm; While the MEFP has a velocity between 1 500 and 1 750 m/s with an even distribution and can penetrate through the 45 steel targets with a thickness of 6 mm. The obtained results provide important reference to the design of dual-mode warhead.
