T1 - Mode-coupling theory of shear and sound relaxation in viscous supercooled liquids
AU - Marchetti, M. Cristina
PY - 1986

N2 - A generalized mode-coupling theory of shear and ultrasonic relaxation in viscous supercooled molecular liquids is presented. The theory is based on ideas recently proposed to describe dynamical properties of dense simple liquids and then extended by several authors to discuss the glass transition in such systems. The mode-coupling theory naturally involves a continuum of relaxation times leading to a nonexponential decay of the response to mechanical shear and compressional disturbances. The theory provides a good fit of shear and ultrasound data in supercooled molecular liquids over the entire relaxation region.
