Forced deterministic dynamics on a random energy landscape: Implications for the physics of amorphous solids

A Szulc, O Gat, I Regev - Physical Review E, 2020 - APS
The dynamics of supercooled liquids and plastically deformed amorphous solids is known to
be dominated by the structure of their rough energy landscapes. Recent experiments and …

Topology of the energy landscape of sheared amorphous solids and the irreversibility transition

I Regev, I Attia, K Dahmen, S Sastry, M Mungan - Physical Review E, 2021 - APS
Recent experiments and simulations of amorphous solids plastically deformed by an
oscillatory drive have found a surprising behavior—for small strain amplitudes the dynamics …

Annealing and rejuvenation in a two-dimensional model amorphous solid under oscillatory shear

E Schinasi-Lemberg, I Regev - Physical Review E, 2020 - APS
We study the annealing and rejuvenation behavior of a two-dimensional amorphous solid
model under oscillatory shear. We show that, depending on the cooling protocol used to …

Onset of irreversibility and chaos in amorphous solids under periodic shear

I Regev, T Lookman, C Reichhardt - … Review E—Statistical, Nonlinear, and Soft …, 2013 - APS
A fundamental problem in the physics of amorphous materials is understanding the
transition from reversible to irreversible plastic behavior and its connection to yield …

Amorphous systems in athermal, quasistatic shear

CE Maloney, A Lemaitre - Physical Review E—Statistical, Nonlinear, and Soft …, 2006 - APS
We present results on a series of two-dimensional atomistic computer simulations of
amorphous systems subjected to simple shear in the athermal, quasistatic limit. The …

Plastic response of a 2d amorphous solid to quasi-static shear: Ii-dynamical noise and avalanches in a mean field model

A Lemaître, C Caroli - arXiv preprint arXiv:0705.3122, 2007 - arxiv.org
We build a minimal, mean-field, model of plasticity of amorphous solids, based upon a
phenomenology of dissipative events derived, in a preceding paper [A. Lemaitre, C. Caroli …

Critical diffusivity in the reversibility–irreversibility transition of amorphous solids under oscillatory shear

I Regev, T Lookman - Journal of Physics: Condensed Matter, 2018 - iopscience.iop.org
Recently it was shown that under oscillatory shear at zero temperature an amorphous solid
transitions from asymptotically periodic to asymptotically diffusive steady-state at a critical …

On the relevance of disorder in athermal amorphous materials under shear

E Agoritsas, E Bertin, K Martens, JL Barrat - The European Physical …, 2015 - Springer
We show that, at least at a mean-field level, the effect of structural disorder in sheared
amorphous media is very dissimilar depending on the thermal or athermal nature of their …

Nonaffine displacements and the nonlinear response of a strained amorphous solid

S Saw, S Abraham, P Harrowell - Physical Review E, 2016 - APS
We demonstrate that irreversible structural reorganization is not necessary for the
observation of yield behavior in an amorphous solid. While the majority of solids strained to …

Dynamics of viscoplastic deformation in amorphous solids

ML Falk, JS Langer - Physical Review E, 1998 - APS
We propose a dynamical theory of low-temperature shear deformation in amorphous solids.
Our analysis is based on molecular-dynamics simulations of a two-dimensional, two …
