Özet

In this study, the high-velocity impact behavior of Ramor 500 armor steel was investigated experimentally and numerically. For this purpose, the steel specimen was impacted by a 9 mm Parabellum full metal jacket (FMJ) bullet at the reliable polygon. On the other hand, the mechanical properties of specimens were found by a tensile test at different temperatures and Johnson-Cook (J-C) parameters were obtained by Split Hopkinson Pressure Bar (SHPB) test data. By using these data, the same test was simulated by ANSYS Explicit Dynamic. Results show that experimental and numerical results provide NIJ LEVEL IIIA conditions. In addition, the perforation thickness of Ramor 500 at the constant projectile velocity and the perforation velocity at the constant thickness were obtained by using ANSYS Explicit Dynamic.
