Numerical simulation of projectile perforation reinforced concrete perpendicularly

Abstract:

This article summarizes the Riedel–Hiermaier–Thoma (RHT) concrete model in detail and demonstrates its basic characteristic by numerical simulation of the single brick element under the uniaxial compression and uniaxial tensile loads. Then the model is applied in the projectile perforation reinforced concrete simulation, both the spallation damage on the front and back face of concrete slab and rupture damage phenomenon in the inner of slab are well presented in the simulation, the residual velocity of projectile predicated by numerical simulation is in good agreement with experimental results reported by Hanchak. Besides, it is also find that there is little influence of the reinforced bar and the similarity angle on deviatoric plane to the residual velocity of projectile in the simulation.
