Investigation of ricochet angles and ballistics research for 5 mm Ti6Al4V, 4340 Steel and Al6061 plates with AP 7.62 bullets

In this study, the effect of a high-speed AP 7.62 bullet on Ti6Al4V, AISI 4340, Inconel-718, AlSi10Mg and Al 6061 - T6 materials at different impact angles were investigated by using finite element package software LS-DYNA 971. 4340 was taken as material 850 m/s speed for ballistic investigation. Angle obliquity against plates has been in range 0-80º. Simulations carried out 5 degrees increments. It that what angle touches materials, will ricochet. Also, deformations have examined. The results showed good correlation with literature. lowest ricochet obtained Inconel-718 20 º followed 25º, Ti6Al4V 55º, 75º lastly 80 º.
