Cover Story: The impact of projectiles into reinforced and unreinforced concrete is a topic that has been investigated in varied research through different approaches and is of importance as concrete is an established material to protect against projectile impact. The influence of projectile tip contour and angle of attack (AoA) on damage and penetration depth of the target has not been reported in the literature before. Accordingly, this paper presents a numerical investigation of a rigid projectile impacting a reinforced concrete target and studies the effects of varying the AoA and tip contour of the projectile, through target damage and projectile penetration.
