“…Among others, one can quote Meppen tests [1], [2], Vulcain tests [3][4][5], or the Iris benchmark (Improving Robustness Assessment Methodologies for Structures Impacted by Missiles) [6] and more recently Xu et al works [7]. Some papers published after Iris benchmark provided finite element simulations of all these tests [8][9][10][11][12][13]. They highlighted different features influencing simulation results such as material models (concrete and steel), strain rate effects, concrete fracture energy or erosion value.…”

This paper provides both an analytical and a finite element model aiming at better predicting possible perforation of reinforced concrete slabs submitted to impacts. Both models account for free water saturation ratio and high triaxial stress induced into concrete by the impact. Finite element simulations are performed with Abaqus explicit code using a revised constitutive model for concrete; this coupled damage plasticity model (PRM) accounts for strain rate effects and the influence of saturation ratio on the triaxial behavior. Complementary original analytical predictions of ballistic limit and residual velocities are provided for both hard and soft impacts. These predictions depend on a recent deviatoric stress-based formulation of compressive strength of concrete. Numerical and analytical results are consistent with bending and punching experimental tests.
