Simulation analysis of the influence of steel bar on kinetic projectile penetrating into reinforced concrete

How the steel bar location and ratio per cube in reinforced concrete target influence the penetration process of kinetic projectile are discussed. Simulation model of kinetic projectile penetrating reinforced concrete was built by a non-linear code AUTODYN-3D. The penetration depth, penetration overloading and damage condition of target are achieved through computation of projectile penetrating in different locations and different steel bar ratios. Research results indicate that projectile penetration depth was mostly affected by the cross steel bar, while increasing the steel bar ratio per cube can improve the capability of target against penetration.
