Numerical simulation of dynamic fracture of concrete target blocks, impacted by steel projectiles, was performed in the present study. The specific impact configuration of this study follows the experiment series conducted by Hanchak et al., where 610 [times] 610 [times] 178mm[sup 3] reinforced concrete blocks were impacted by 25.4 mm diameter, 143.7 mm long, 0.5 kg, 3.0 caliber-radius-head, ogival nose steel rods at impact velocities between 300 and 1000 m/s. The transient dynamic finite element code LS-DYNA2D was used for the numerical analysis. Calculated results were compared to the experimental data. Good correlation was obtained.
