Résumé

To develop numerical tools based on the discrete element method (DEM) to study the relationships between microstructure and thermomechanical properties of model materials. These developments include unbonding, thermomechanical coupling, crack closure, and anisotropic behaviors. These developments will lead to a ''virtual digital laboratory'' capable of providing virtual tensile, dilatometry, fracture mechanics or thermal shock tests for virtual characterizations. The associated developments will be integrated into the free DEM software GranOO.
