Research activities

Research interest : Ceramics - Fracture and damage - Sintering - Discrete simulations - Multi-physics modeling - 3D characterization - Sintering-assisted additive manufacturing

My research activities are focused on the numerical and experimental study of the sintering and the mechanical behavior of ceramic materials, in particular the relation to their microstructure (porous or not). For this purpose, an original modeling based on the discrete elements method has been developed according to two approaches, one adapted to microstructures having a granular character (partially sintered powders) and the other one adapted to continuous media. Beside that, I also work on the modeling of functional properties of these materials, their processing by sintering-assisted additive manufacturing, the 3D characterization of their microstructures and their experimental mechanical characterization.
