The Numerical Simulation of Projectile Penetrating into Steel-Fiber Reinforced Ultra High Strength Concrete Target
Explicit finite element code was applied to simulate the steel fiber reinforced concrete (SFRC) and reactive powder concrete (RPC) target penetrated by kinetic energy projectile. Crater formation, spall of concrete target in penetration process was simulated very well. The numerical results of penetration depths are in good agreement with recent experimental results obtained from ballistic gun with 57 mm caliber. The factors effecting on anti-penetration property of SFRC and RPC are analyzed. The results show that: the compressive strength and toughness of the target body have greater impact on anti-penetration performance in the range of projectile velocity 300 m/s - 600 m/s. Anti-penetration capability of RPC concrete is stronger than that of ordinary steel fiber at the higher speeds.
