Plain concrete targets underwent brittle failure with thick radial cracks due to projectile impact. Crater size in reinforced and prestressed concrete decreased with increase in projectile velocity. Initial prestress proved effective to minimize damage and improve ductility of concrete. Prestressed concrete offered highest resistance followed by reinforced and plain concrete. FE simulations reproduced the ballistic limit of each concrete within 8% deviation.
