We observe nonmonotonic aging and memory effects, two hallmarks of glassy dynamics, in
two disordered mechanical systems: crumpled thin sheets and elastic foams. Under fixed …

Many complex and disordered systems fail to reach equilibrium after they have been
quenched or perturbed. Instead, they sluggishly relax toward equilibrium at an ever-slowing …

Although it has been known for half a century that the physical aging of glasses in
experiments is described well by a linear thermal-history convolution integral over the so …

There is an ever-growing need for predictive models for the elasto-viscoplastic deformation
of solids. Our goal in this paper is to incorporate recently developed out-of-equilibrium …

We investigate the dissipative mechanisms exhibited by creased material sheets when
subjected to mechanical loading, which comes in the form of plasticity and relaxation …

Large-amplitude thermal excursions imposed on deeply supercooled liquids modulate the
nonlinear time evolution of their structural rearrangements. The consequent aftereffects are …

This paper presents accurate data for the physical aging of organic glasses just below the
glass transition probed by monitoring the following quantities after temperature up and down …

This paper derives and discusses the configuration-space Langevin equation describing a
physically aging R-simple system and the corresponding Smoluchowski equation. Externally …

The Bochkov-Kuzovlev nonlinear fluctuation-dissipation theorem is used to derive
Narayanaswamy's phenomenological theory of physical aging, in which this highly …

This paper presents physical-aging data for the silicone oil tetramethyl-tetraphenyl
trisiloxane. The density and the high-frequency plateau shear modulus G∞ were monitored …
