This study presents the problem of achieving multimode penetrator conversion. By using the same shaped charge and by changing the position of point initiation, the trial demonstrates two types of the penetrator, which are the explosively formed penetrator (EFP) and the rod-shaped EFP. Compared with the EFP, the penetration depth of the rod-shaped EFP is 2.17 times higher, and the penetration aperture only decreases by 31.8%.
