3D coupling approach between discrete and continuum models for dynamic simulations (DEM-CNEM)

Résumé

The coupling between two dissimilar numerical methods presents a major challenge, especially in case of discrete-continuum coupling. The Arlequin approach provides a flexible framework and presents several advantages in comparison to alternative approaches. Many studies have analyzed, in statics, the ingredi-ents of this approach in 1D configurations under several particular conditions. The present study extends the Arlequin parameter studies to incorporate a dynamic behavior using 3D models. Based on these stud-ies, a new 3D coupling method adapted for dynamic simulations is developed. This method couples two 3D codes: DEM-based code and CNEM-based code. The 3D coupling method was applied to several ref-erence dynamics tests. Good results are obtained using this method, compared with the analytical and numerical results of both DEM and CNEM.
