1 LTN - Laboratoire de thermocinétique [Nantes]

An experimental investigation of the solid ?uid transition in a yield stress shear thinning physical gel (Carbopol) under shear is presented. The first part of the talk would describe in detail each deformation regime with a particular focus on the irreversibility of the deformation states. A simple model will be presented. The second part of the talk will demonstrate the thermorheological complexity of Carbopol gels under shear.
