Slow flows of yield stress fluids: complex spatio-temporal behaviour within a simple elasto-plastic model
Guillemette Picard, Armand Ajdari, Francois Lequeux +1
A minimal athermal model for the flow of dense disordered materials is proposed, based on two generic ingredients: local plastic events occuring above a microscopic yield stress, a…

Elastic consequences of a single plastic event : a step towards the microscopic modeling of the flow of yield stress fluids
Guillemette Picard, Armand Ajdari, Francois Lequeux +1
With the eventual aim of describing flowing elasto-plastic materials, we focus on the elementary brick of such a flow, a plastic event, and compute the long-range perturbation it e…
