Aiming at the effect of different length-to-diameter ratio of charge in EFP shaping, the process of a kind of hemispherical EFP shaping is modeled and simulated with ANSYS/LS-DYNA simulation software. The process of EFP shaping and parameters of the processing are studied. The different data of length-to-diameter ratio of charge are obtained by changing the height of charge, and then the process of shaping in different length-to-diameter ratio is simulated to receive the data of velocity, speed growth rate and energy efficiency of different length-to-diameter ratio, which provides the theoretical basis in designing and manufacturing and the damage effect evaluation of EFP.
