| Abstract |
The ballistic resistance of a flat surface and a slanted surface ceramic metal bi-layer armour has been compared against blunt nosed projectile impact. The bi-layer targets have been made up of alumina 95% and aluminium alloy 2024-T3, front and back layer, respectively. The ballistic resistance of the targets has been compared against impact of steel 4340 blunt nosed flat tip cylindrical projectile. The numerical simulation model has been developed using Abaqus/Explicit finite element code. The behaviour of ceramic and metal under ballistic impact has been modelled by using the widely used constitutive models, JH-2 and JC, respectively. The developed numerical model has been validated by using the available experimental results. The validated numerical model has been further used to study the ballistic behaviour by comparing the residual velocity of the projectile and the damage induced in the target as well as the projectile. A significant variation has been observed in the ballistic resistance of the target with small change in the surface profile of the target. The comparison of the ballistic resistance offered by both the targets against eccentric impact load have also been carried out. |
