Séminaire PMMH - Denis Dumont (IUSTI Marseille)
Rheology of sticky grains
In many powder technology processes, coating is applied to fine particles to control their properties or functionalize them. We investigated the role of a polymer coating made of PBS on silica beads. This material has been originally designed as a model cohesive granular material, whose cohesion can be finely controlled by the thickness of the coating (A. Gans et al 2020). However, we show that the coating not only introduces adhesion but also modifies the friction between the grains. Due to the viscoelastic properties the coating, the inter-particle friction coefficient depends on the load and the velocity. By means of numerical DEM simulations, we demonstrate that this transition in the inter-particle friction coefficient can induces complex behavior for the bulk rheology such as shear-thickening and shear-banding.

Séminaire PMMH - Vince Craig, Australian National University, Australia
Vendredi 11 juillet de 11h00 à 12h00 - Salle réunion PMMH 1
Underscreening Stable colloidal systems at very high electrolyte concentrations
In colloidal systems the range and strength of electrostatic interactions has a profound effect on a range of properties including the stability of colloidal dispersions and the phase behaviour of surfactant and polymer systems. The Debye length has proven to be a very effective measure of the range of (…) -
Séminaire PMMH - Salvatore Federico (University of Calgary, Canada)
Vendredi 4 juillet de 11h00 à 12h00 - Salle réunion PMMH 1
Continuum Mechanics of Hydrated Fibre-Reinforced Soft Tissues
Biological tissues can be represented as bi-phasic continua, with a porous solid phase saturated by an interstitial fluid and reinforced by collagen fibers. This lecture will give an overview of the modelling techniques for fibre-reinforced porous composite materials with statistical orientation of the fibers. Both (…) -

REPROGRAMMABLE HARDWARE FOR DATA PROCESSING AT THE EDGE : A NEW COMPUTING PARADIGM BASED ON NEUROMORPHIC SYSTEMS
The brain's ability to perform efficient and fault-tolerant data processing is strongly related with its peculiar interconnected adaptive architecture, based on redundant neural circuits interacting at different scales. By emulating the brain's processing and learning mechanisms, computing technologies strive to (…) -

Séminaire PMMH – Vincent Bertin (IUSTI, U. Aix-Marseille)
Vendredi 6 juin de 11h00 à 12h00 - Salle réunion PMMH 1
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
