In some dry contacts, such as in fretting, the relative motion between the two bodies generates particles of wear debris. These debris particles, mixed with external particles, form the third body. This third body plays several roles, and in particul

Flows of suspensions can be blocked when the suspended particles are densely packed. Here, we study suspensions of industrial rough silica particles in a Newtonian fluid. The rheological behavior with and without vibrations is study at a volume fract

In order to model the behavior of geometarials under complex loadings, several researches have done numerous experimental works and established relative constitutive models for decades. An important feature of granular materials is that the relations

Bentonite based materials are considered as a sealing material in radioactive waste disposal concepts because of their low permeability, radionuclide retention capacity and ability to swell upon hydration, thus filling technological gaps. Within this

Les avalanches de plaque représentent un risque naturel majeur dont la prévision demeure très difficile. Le manque de lois constitutives fiables à l’échelle du matériau rend difficiles les tentatives de modélisation de ce phénomène. Plus s

Dry slab snow avalanches represent a major natural hazard that is extremely difficult to manage. Attempts to model this phenomenon are hindered by the lack of a constitutive law that would describe the mechanical behaviour of snow on a material scale

When a homogeneous stress is applied on a granular material, it first, shows a homogeneous strain and then, above a certain threshold, a heterogeneous strain. However, underlying plasticity mechanisms which trigger this behavior are not known very we
