Multiple yielding processes in a colloidal gel under large amplitude oscillatory stress
Thomas Gibaud, Christophe Perge, Stefan B. Lindstrom +2
Fatigue refers to the changes in material properties caused by repeatedly applied loads. It has been widely studied for, e.g., construction materials, but much less has been done o…
Time dependence in large amplitude oscillatory shear: a rheo-ultrasonic study of fatigue dynamics in a colloidal gel
Christophe Perge, Nicolas Taberlet, Thomas Gibaud +1
We report on the response of a yield stress material, namely a colloidal gel made of attractive carbon black particles, submitted to large amplitude oscillatory shear stress (LAOSt…
Creep and Fracture of a Protein Gel under Stress
Mathieu Leocmach, Christophe Perge, Thibaut Divoux +1
Biomaterials such as protein or polysaccharide gels are known to behave qualitatively as soft solids and to rupture under an external load. Combining optical and ultrasonic imaging…
Inertio-elastic instability of non shear-banding wormlike micelles
Christophe Perge, Marc-Antoine Fardin, Sebastien Manneville
Homogeneous polymer solutions are well-known to exhibit viscoelastic flow instabilities: purely elastic when inertia is negligible, inertio-elastic otherwise. Recently, shear-bandi…
Shear-induced structures versus flow instabilities
Marc-Antoine Fardin, Christophe Perge, Nicolas Taberlet +1
The Taylor-Couette flow of a dilute micellar system known to generate shear-induced structures is investigated through simultaneous rheometry and ultrasonic imaging. We show that f…
Surfactant micelles: model systems for flow instabilities of complex fluids
Christophe Perge, Marc-Antoine Fardin, Sebastien Manneville
Complex fluids such as emulsions, colloidal gels, polymer or surfactant solutions are all characterized by the existence of a "microstructure" which may couple to an external flow…
