Abstract :Penetration is the most critical concept in ballistic studies. Penetration is defined as the ability to penetrate the target. Penetrator tip geometry and velocity are the most important factors in terms of the penetration. There are many limitations in increasing the velocity of the penetrator. Therefore, projectile geometry can be studied in this field. So, in this study, six different tip geometry of bullet are investigated in terms of the ballistic impact performance. Numerical simulations are performed in ANSYS program, which is the finite element program. Explicit dynamics toolbox is used to perform the numerical study. Six different tip geometry of bullet was modeled in 3D modeling program. The geometries are transferred to the ANSY workbench program. Initial velocity is accepted as 300 m/s for all conditions. Within this study, the impact energy performance of six different bullet tip geometry was obtained. In addition, stress and deformation results on the target were also compared.
