Abstract
This paper describes the numerical modeling of projectile impact on cement based composite slabs. In the simulated experiment, local damage is inflicted by impact of defined projectiles on specimens made from normal strength concrete (NSC), ultra-high performance concrete (UHPC) and ultra-high performance fiber-reinforced concrete (UHPFRC). Deformable ogive-nose projectiles with diameter of 7.92 mm and mass of 8.0 g with impact velocity about 700m/s were used in the modeled experiment, hitting center of the specimens. Data from the measured and visual evaluation of specimen damage were used for comparison of specimen projectile impact resistance in relation to the used material and compared to the numerical prediction.
