Bulk and shear relaxation in glasses and highly viscous liquids

Disordered Systems and Neural Networks 2016-04-19 v4

Abstract

The ratio between the couplings of a relaxational process to compression and shear, respectively, is calculated in the Eshelby picture of structural rearrangements within a surrounding elastic matrix, assuming a constant density of stable structures in distortion space. The result is compared to experimental data for the low-temperature tunneling states in glasses and to Prigogine-Defay data at the glass transition from the literature.
