Timescales in creep and yielding of attractive gels
Vincent Grenard, Thibaut Divoux, Nicolas Taberlet +1
The stress-induced yielding scenario of colloidal gels is investigated under rough boundary conditions by means of rheometry coupled to local velocity measurements. Under an applie…
Ultrafast ultrasonic imaging coupled to rheometry: principle and illustration
Thomas Gallot, Christophe Perge, Vincent Grenard +3
We describe a technique coupling standard rheology and ultrasonic imaging with promising applications to characterization of soft materials under shear. Plane wave imaging using an…
Rheological hysteresis in soft glassy materials
Thibaut Divoux, Vincent Grenard, Sébastien Manneville
The nonlinear rheology of a soft glassy material is captured by its constitutive relation, shear stress vs shear rate, which is most generally obtained by sweeping up or down the s…
Shear-induced structuration of confined carbon black gels: Steady-state features of vorticity-aligned flocs
Vincent Grenard, Nicolas Taberlet, Sebastien Manneville
Various dispersions of attractive particles are known to aggregate into patterns of vorticity-aligned stripes when sheared in confined geometries. We report a thorough experimental…
Fluctuation-dissipation relation on a Melde string in a turbulent flow, considerations on a "dynamical temperature"
Vincent Grenard, Nicolas Garnier, Antoine Naert
We report on measurements of the transverse fluctuations of a string in a turbulent air jet flow. Harmonic modes are excited by the fluctuating drag force, at different wave-number…
