We study a mean field elastoplastic model, embedded within a disordered landscape of
local yield barriers, to shed light on the behavior of athermal amorphous solids subject to …

Slow fatigue and highly delayed yielding via shear banding in oscillatory shear

JO Cochran, GL Callaghan, MJG Caven… - Physical Review Letters, 2024 - APS
We study theoretically the dynamical process of yielding in cyclically sheared amorphous
materials, within a thermal elastoplastic model and the soft glassy rheology model. Within …

Aging in a mean field elastoplastic model of amorphous solids

JT Parley, SM Fielding, P Sollich - Physics of Fluids, 2020 - pubs.aip.org
We construct a mean-field elastoplastic description of the dynamics of amorphous solids

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 …

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 …

Mean-field description of aging linear response in athermal amorphous solids

JT Parley, R Mandal, P Sollich - Physical Review Materials, 2022 - APS
We study the linear response to strain in a mean-field elastoplastic model for athermal
amorphous solids, incorporating the power-law mechanical noise spectrum arising from …

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 …

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 …

Metastability as a mechanism for yielding in amorphous solids under cyclic shear

M Mungan, S Sastry - Physical review letters, 2021 - APS
We consider the yielding behavior of amorphous solids under cyclic shear deformation and
show that it can be mapped into a random walk in a confining potential with an absorbing …

Towards a complete mean-field theory for the ductile and brittle yielding of amorphous solids: beyond the paradigm of the Ising model in a random field

JT Parley, P Sollich - arXiv preprint arXiv:2310.07843, 2023 - arxiv.org
Developing a unified theory describing both ductile and brittle yielding constitutes a
fundamental challenge of non-equilibrium statistical physics. Recently, it has been proposed …
