Numerical investigation of the ballistic effect of tungsten alloy kinetic energy ammunation on boron carbide reinforced 4340 steel plates

The tanks that took part in the First World War have made significant progress during the Second World War. Because of the superiority of armored vehicles on the battlefield, both armor technology and ammunition technology are developing rapidly nowadays. In this study, the effect of tungsten alloy kinetic energy ammunition penetrator on 4340 steel and boron carbide armor plates was investigated by finite elements methods. The required material parameters for the finite element model (Johnson-Cook, Johnson-Holmquist) were determined. Within the domain of ammunition, three-dimensional analysis of the impactor by multiplication of the penetrator at different collision angles was done by numerical analysis. In the collision analysis at different angles, it was observed that the penetrator pierced the armor. The penetrator speed of 1750m / s was found to decrease to 1513.16 m / s after drilling the 0 degree angle armor. In the analysis of the armor at 15 degrees angle, the velocity was found to be 1463 m / s after the collision. The analysis of the armor at 30 degrees was observed to be 1390.1 m / s after the collision. Finally, after the collision in the collision analysis of the armor at 45 degrees, the velocity was found to be 1269.5 m/s. Stresses and deformations in armor and ammunition are presented.
