Damage resistance investigation of different plates subjected to impact loads

Damage resistance of target plates to the ballistic loads is an important design parameter while designing the structures that will be subjected to these loads. The study of target plates under the normal and oblique ballistic loads contributes to understandings of performance of the structures that are produced using these plates and are subjected to the ballistic loads under the different oblique angles. It is important to investigate the resistance of materials exposed to low and high-velocity loads. Metals, fiber-reinforced composites, sandwich panels, and different combinations of these materials are used in the design of structures that will withstand these loads. In this thesis, first of all, the design and production of the impact test set-up for testing high-speed impact loads are done. Then, Basalt fiber-reinforced composite materials are produced. In this thesis, 3, 6, 9, and 12 layers composite plates are produced with cross-ply orientation. The initial velocity and final velocity of the projectile are compared and energy absorption capacities of target plates are determined. Also, a numerical investigation on the ballistic impact resistance of different aluminum alloys and basalt/epoxy is performed. In the numerical part, the effects of the oblique angles are also researched. There is a nearly 13 (nearly 1195 %) times difference between the absorbed energy of 3 layer target plate and 12 layer target plate.
