Internal relaxation time in immersed particulate materials
P. Rognon, I. Einav, C. Gay
We study the dynamics of the solid to liquid transition for a model material made of elastic particles immersed in a viscous fluid. The interaction between particle surfaces includ…
A tentative geometrical description of static dilatancy in liquid foams: ordered 2D and 3D foams
Pierre Rognon, François Molino, Cyprien Gay
Liquid foams have been observed to behave like immersed granular materials in at least one respect: deformation tends to raise their liquid contents, a phenomenon called dilatancy.…
Plateau border bulimia transition: discontinuities expected in three simple experiments on 2D liquid foams
Pierre Rognon, François Molino, Cyprien Gay
We describe the geometry of foams squeezed between two solid plates (2D GG foams) in two main asymptotic regimes: fully dry floor tiles and dry pancakes. We predict an abrupt trans…
Soft Dynamics simulation: 2. Elastic spheres undergoing a T1 process in a viscous fluid
Pierre Rognon, Cyprien Gay
Robust empirical constitutive laws for granular materials in air or in a viscous fluid have been expressed in terms of timescales based on the dynamics of a single particle. Howeve…
