Physical origin of shear-banding in jammed systems
Philippe Coussot, Guillaume Ovarlez
Jammed systems all have a yield stress. Among these materials some have been shown to shear-band but it is as yet unclear why some materials develop shear-band and some others do n…
Transition from a simple yield stress fluid to a thixotropic material
Alexandre Ragouilliaux, Guillaume Ovarlez, Noushine Shahidzadeh-Bonn +3
From MRI rheometry we show that a pure emulsion can be turned from a simple yield stress fluid to a thixotropic material by adding a small fraction of colloidal particles. The two…
Phenomenology and physical origin of shear-localization and shear-banding in complex fluids
Guillaume Ovarlez, Stéphane Rodts, Xavier Chateau +1
We review and compare the phenomenological aspects and physical origin of shear-localization and shear-banding in various material types, namely emulsions, suspensions, colloids, g…
