Perspective: Supercooled liquids and glasses
Mark Ediger,Peter Harrowell +1 more
TL;DR: The connections between amorphous structure, high frequency motions, molecular motion, structural relaxation, stability against crystallization, and material properties, and the interpretation of supercooled liquid and glass properties in terms of the potential energy landscape is explored.

A thermoviscoelastic model for amorphous shape memory polymers: Incorporating structural and stress relaxation
TL;DR: A thermoviscoelastic constitutive model is developed for amorphous shape memory polymers (SMP) based on the hypothesis that structural and stress relaxation are the primary molecular mechanisms of the shape memory effect and its time-dependence as mentioned in this paper.
Journal ArticleDOI
Direct measurement of molecular mobility in actively deformed polymer glasses.
TL;DR: An optical photobleaching technique is used to quantitatively measure changes in molecular mobility during the active deformation of a polymer glass, observing a strong correlation between strain rate and segmental mobility during creep.

On the Temperature Dependence of Cooperative Relaxation Properties in Glass‐Forming Liquids
Gerold Adam,Julian H. Gibbs +1 more
TL;DR: In this paper, a molecularkinetic theory was proposed to explain the temperature dependence of relaxation behavior in glass-forming liquids in terms of the temperature variation of the size of the cooperatively rearranging region.

A Model of Structural Relaxation in Glass
TL;DR: In this paper, a multiparameter model of structural relaxation is presented that differs from earlier models in that it takes account of both the memory effect and the inherent nonlinearity which are characteristic of structural relaxations.
