Discrete Element Analysis to Predict Penetration and Perforation of Concrete Targets Struck by Rigid Projectiles
This chapter presents a discrete element method (DEM) approach implemented in EUROPLEXUS, fast dynamic software, which is able to predict damage of concrete structures under severe impacts. The increasing demand for infrastructure security requires accounting for the severe dynamic loading due to natural or man‐made hazards such as aircraft impacts. The DEM is a powerful alternative to the finite element method (FEM) for studying advanced damage states and failure of concrete. Discrete elements are spheres of different sizes and masses; they do not represent the constituents of concrete such as aggregates. In the proposed method, the concrete structure is modeled by a disordered polydisperse assembly of rigid spherical elements with different sizes and masses obtained using a geometric algorithm based on a tetrahedral finite element mesh. The nonlinear constitutive behavior of plain uncracked concrete is modelled by means of a cohesive link between two discrete elements.
