Study of Ballistic Impact Effect with Finite Element Method

In this study, dynamic response of exposure to a high-speed impact of Titanium, TI 6%AL4%V and Steel 4340 plates were investigated depending on increasing thickness of plates and the changing impactor geometry using finite element method. The plates were modeled using 200×200 mm size and 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm and 7 mm thickness. The impactor’s material is Steel 4340 and for all analysis it has 350 m/s velocity. Four edges of the plates are fixed and the impact loads applied to center of the plates. Finite element analysis was performed using ANSYS/ Workbench/ Autodyn. As a result, the relation between displacement - thickness and damped energy – thickness are given in graphics.
