Abstract

Explosively formed projectiles (EFP) are very much used in antiballistic missiles and the indigenous development is under process. Optimization studies have to be carried out for maximum penetration and damage for which the influencing factors are the shape of the projectile formed and its kinetic energy. Liner geometry is one of the important parameters that affects the shape and kinetic energy of the projectile. As parametric studies require lot of experimentation that is costly and time consuming numerical studies are essential to arrive nearer to solution, hence in this work numerical studies are carried out to find the effect of liner thickness and liner diameter on the shape and the energy of the projectile formed.
