Abstract: To overcome the difficulty of dealing extra large deformation problem with finite element method（FEM）, projectile penetrating into steel fiber reinforced concrete were simulated using a coupled method berween smoothed particle hydrodynamics（SPH）and finite element abalysis. The projectiles were treated using standard Lagrangian finite elements and considered as rigid but the targets were divided into SPH grids subjected to large strains, high strain rates, and high pressures. To describe nonlinear deformation and fractural characteristics of steel fiber reinforced concrete, Holmquist–Johnson–Cook constitutive relations and damage model were introduced into computations. The numerical simulation revealed well the physical process of experimental damage image of the splash crater formation of the targets. Particularly, the numerical simulation results of concrete debris spattering fit well with the high-speed camera photos. The numerical simulation results of penetration depth in good agreed well with the experimental data. The study showed that steel fiber has an obvious strengthening effect on concrete targets to resist the penetration of projectiles，and such anti-penetration ability increases with the increase in fiber fraction．
