An MCT model of suspension rheology

Concentrated suspensions possess interesting rheological properties. For example, upon increasing the shear rate past some critical value, there can be a large jump (1-2 orders of magnitude) in the sample's shear stress/viscosity. Further, it appears that by similar mechanical forcing of the sample, it may be possible to jam it into a solid state. It has been speculated that such a 'jammed solid' may be a form of glass. In the talk, I will discuss a model in which the transition to the solid 'jammed' state is treated a stress-induced glass transition within the framework of (simplified) mode-coupling theory.
