A non-local rheology for dense granular flows.
A non-local theory is proposed to model dense granular flows. The idea is to describe the rearrangements occurring when a granular material is sheared as a self-activated process. A rearrangement at one position is triggered by the stress fluctuations induced by rearrangements elsewhere in the material. Within this framework, the constitutive law, which gives the relation between the shear rate...
متن کاملRheology of soft colloids across the onset of rigidity: scaling behavior, thermal, and non-thermal responses.
We study the rheological behavior of colloidal suspensions composed of soft sub-micron-size hydrogel particles across the liquid-solid transition. The measured stress and strain-rate data, when normalized by thermal stress and time scales, suggest our systems reside in a regime wherein thermal effects are important. In a different vein, critical point scaling predictions for the jamming transit...

Scaling laws in the rheology of colloidal dispersions
In this thesis, starting from a schematic mode-coupling model, the dynamics and the ow behavior of colloidal dispersions under stationary shearing close to the glass transition is analyzed. Both analytical and numerical methods are applied. The most important control parameters of the model are the shear rate and the separation parameter measuring the distance from the glass transition point. A...
متن کاملNon-local scaling in two–dimensional gravitational clustering
Using an ensemble of high resolution 2D numerical simulations, we explore the scaling properties of cosmological density fluctuations in the non-linear regime. We study the scaling behaviour of the usual N–point volume-averaged correlations, but also examine the scaling of the entire probability density function (pdf) of the fluctuations. We focus on two important issues: (i) whether the scalin...
