Title: Coupling discrete element simulations to tomographic images: from elasticity to fracture.

The possibilities offered by coupling X-ray tomographic images and the Discrete Element Method (DEM) are presented. DEM is a very effective alternative to the Finite Element Method or the Fast Fourier Transform when fracture is considered. The topological modifications that come with fracture are easier to capture with DEM. This type of simulation should give valuable insights on the fracture mechanisms of porous and non-porous materials at the pertinent length scale. The general principles of DEM are presented and application examples are discussed.

Biography: Christophe Martin is a CNRS Senior Researcher at SIMaP laboratory at the Univ. Grenoble Alpes. He is the principal investigator of a discrete element code, dp3D, dedicated to the processing of powders and to the investigation of the fracture behaviour of brittle materials.
