Simulation Analysis on Local Damage to Reinforced Concrete Panels Subjected to Oblique Impact by Different Projectiles

Analytical study of perforation damage in reinforced concrete slabs subjected to oblique impact by projectiles with different nose shapes

“…For oblique impact, there is only a few experimental results available for research and Ohta et al (2017) developed a new formula to predict local damage induced by oblique impact of rigid projectile based on test data (Richard and Stipe, 1943) by means of integrating correction factors regarding projectile diameter, slip and rebound effects with the modified NDRC formula (Kennedy, 1976). Recently, simulation analysis for evaluation of the penetration and perforation damage to RC slabs subjected to oblique impact has been conducted and corresponding interpretation on analytical results has been provided in detail (Nishida et al, 2018(Nishida et al, , 2019Kang et al, 2019Kang et al, , 2020.…”
