Simulation numérique de l'endommagement de dalles en béton armé impactées par un réacteur d'avion idéalisé

Abstract : In this paper, we present numerical simulations of impact of idealized planes engines on reinforced concrete structures. This impact produce local damage phenomena of the structure. Those can be characterized by a cratering of the concrete slab under the impact, a phenomenon of scabbing on the opposite face and possibly a perforation by the engine. In an industrial context, this problem is in general dealt with empirical formulas which do not take into account the interaction between the projectile and the slab. We show here that numerical simulations using a concrete behavior adapted make it possible to account for the interaction between the projectile and the structure and thus to better apprehend the local phenomena.
