Scission of flexible polymers in contraction flow: predicting the effects of multiple passages
Sandeep Garrepally, Stephane Jouenne, Peter D. Olmsted +1
When injected through a contraction, high molecular weight polymer solutions exhibit a sharp increase of apparent viscosity which originates from stretching polymer chains above a…
Probing thermal waves on the free surface of various media: Surface Fluctuation Specular Reflection Spectroscopy
Astrid Tay, Caroline Thibierge, Danièle Fournier +5
Thermal motion gives rise to fluctuations in free surfaces; the propagation of the thermally excited waves on such surfaces depends on the mechanical properties of the medium. Thei…
Subdiffusion and dynamical heterogeneities in a lattice glass model
Eric Bertin, Jean-Philippe Bouchaud, Francois Lequeux
We study a kinetically constrained lattice glass model in which continuous local densities are randomly redistributed on neighbouring sites with a kinetic constraint that inhibits…
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…
Aging and effective delays in colloidal glasses under shear
Virgile Viasnoff, Francois Lequeux
In this paper we analyze the changes in the microscopic dynamics of a colloidal glass submitted to an oscillatory shear. We use Multispeckle diffusing Wave Spectroscopy to monitor…
