This PhD is one of the one of 15 PhD’s of the CESAREF European project (www.cesaref.eu )

Objectives: To conduct developments of numerical tools based on the discrete element method (DEM) for investigation of the relationships between microstructure and thermomechanical properties of model materials. These developments include debounding, thermomechanical coupling, crack-closure and anisotropic behaviours. These developments will lead to a “virtual numerical lab” able to provide tensile, dilatometry, fracture mechanics or thermal shock virtual tests for virtual characterizations. The related developments will be integrated to the free DEM software GranOO.

Expected Results: Validation of the method in regard to experimental observations in terms of (i) mesoscopic thermomechanical quantities such as CTE, Young’s modulus, Poisson’s ratio, stress-strain law and fracture energy and (ii) microscopic observations such as fracture coalescence under thermal and mechanical loadings dynamically observed in SEM.
