This research explores the ability of 60 mm thick reinforced concrete (RC) plates to resist impacts from ogive-nosed hard steel projectiles. The projectiles used in the present study have a diameter of 19 mm, a length of 200 mm, and a mass of 0.4 kg impacted on the RC plates with incident velocities ranging from 92 m/s to 161 m/s. Numerical simulations were conducted using ABAQUS/Explicit finite element software to validate the experimental results. The Holmquist–Johnson–Cook (HJC) material model was employed to simulate the constitutive behavior of concrete, while the Johnson–Cook (JC) material model was used to simulate the material response of reinforcing steel bars. The residual velocities obtained from the simulations closely matched the actual experimental results, showing a polynomial correlation with the incidence velocities of the projectiles. Moreover, the experimentally and numerically determined ballistic limit for the 60 mm thick RC plate was found to be 108 m/s and 109.5 m/s, respectively. In contrast, the ballistic limit calculated using empirical mathematical expressions was 107.4 m/s. This alignment between predicted, calculated, and actual ballistic limits underscores the reliability and accuracy of both numerical and empirical approaches. [ABSTRACT FROM AUTHOR]
