Abstract:
The effect of the liner material density and elongation on the shape of dual mode penetrators is studied by using the LS-DYNA software. Characteristics of liners made of five types of materials (aluminum, pure iron, copper, tantalum, and tungsten) under the same conditions of the liner volume or liner mass are compared. It is established that it is better to choose liner materials with good dynamic elongation and moderate density, such as pure iron and copper, to form good dual mode penetrators, namely, the explosively formed penetrator (EFP) and the jetting projectile charge (JPC). Characteristics of penetrators formed from aluminum, steel 20, and copper are considered. The simulation results are in good agreement with x-ray imaging experimental results.
Keywords:
liner material, explosively formed penetrator (EFP), jetting projectile charge (JPC), density, elongation, numerical simulation.
