Abstract
The purpose of the present work is to introduce a limited set of kinetic equations which describe the out-of-equilibrium relaxation of a structural glass and its response to shear deformation. It was originally motivated by recent theories for the plasticity of amorphous solids, [4, 5] in an attempt to incorporate glassy relaxation at an elementary level. [8, 9] A quite simple picture emerges, which accounts for important properties of glassy materials, while its premises may hold for general classes of complex fluids; [7] it echoes early theories of structural relaxation [1,10,11,14] in a much more systematic framework, and provides theoretical grounding for phenomenological rateand- state equations.
