Numerical modeling of temperature field on high velocity explosively formed projectile

Abstract

Paper expose the forming of Explosively Formed Projectiles (henceforth EFP) used for the special types of warheads. Model is designed without metal covers of explosive charge in order to represent temperature effects on melted core (henceforth liner) of EFP, powered by initial explosive shocks waves and realized velocities. Presented numerical approach of temperature and dynamical calculations at the very beginning of initiation has aim to estimated performances of EFP regarding forming dynamics, energies, projectile shapes and initial velocities.
