Creep deformation of glasses under shear stress, results from a schematic mode-coupling model — •Fabian Frahsa and Matthias Fuchs — Fachbereich Physik, Universität Konstanz, 78457 Konstanz, Germany

The viscoelasticity of dense colloidal dispersions causes creep deformation under constant stress. Creep provides insight in the slow structural dynamics and dissipative processes of glasses.

We present predictions for the stress-driven rheology of glass from a schematic model of the mode-coupling theory (MCT) and compare them with experiments of core-shell micro gels. The schematic model is motivated by the microscopic ITT-MCT approach to the stress response of flow-driven systems and covers incompressible and homogeneous flows neglecting hydrodynamic interactions.
