Advanced simulation of damage of reinforced concrete structures under impact / S. Potapov in European journal of environmental and civil engineering, Vol. 16 N° 9 (special issue) (Octobre 2012)

Potapov, Auteur ; V. Faucher, Auteur ; L. Daudeville, Auteur Année de publication : 2012 Article en page(s) : pp. 1090-1101 Note générale : Génie Civil Langues : Français (fre) Mots-clés : Discrete  elements  Finite  elements  Coupling  Fast  dynamics  Parallelism Résumé : The efficiency of the discrete element method for studying the fracture of heterogeneous media has been demonstrated, but it is limited by the size of the computational model. A coupling between the discrete element and the finite element methods is proposed to handle the simulation of impacts on large structures. The structure is split into sub-domains in each of which the method of analysis is adapted to optimise the modelling of the structure behaviour under impact. The DEM takes naturally into account the discontinuities and is used to model the media in the impact zone. The remaining structure is modelled by the FEM. Proposed combined DE/FE algorithm is implemented in the EUROPLEXUS fast dynamics software and parallelised with MPI formalism. The efficiency of the EUROPLEXUS multi-domain MPI parallel version is tested.
