Deformation and flow of amorphous solids: Insights from elastoplastic models

A Nicolas, EE Ferrero, K Martens, JL Barrat - Reviews of Modern Physics, 2018 - APS
The deformation and flow of disordered solids, such as metallic glasses and concentrated
emulsions, involves swift localized rearrangements of particles that induce a long-range …

Non-local rheology in dense granular flows: Revisiting the concept of fluidity

M Bouzid, A Izzet, M Trulsson, E Clément… - The European Physical …, 2015 - Springer
The aim of this article is to discuss the concepts of non-local rheology and fluidity, recently
introduced to describe dense granular flows. We review and compare various approaches …

Scaling description of the yielding transition in soft amorphous solids at zero temperature

J Lin, E Lerner, A Rosso… - Proceedings of the …, 2014 - National Acad Sciences
Yield stress materials flow if a sufficiently large shear stress is applied. Although such
materials are ubiquitous and relevant for industry, there is no accepted microscopic …

Emergence of cooperativity in plasticity of soft glassy materials

A Le Bouil, A Amon, S McNamara, J Crassous - Physical review letters, 2014 - APS
The elastic coupling between plastic events is generally invoked to interpret plastic
properties and the failure of amorphous soft glassy materials. We report an experiment …

Local and global avalanches in a two-dimensional sheared granular medium

J Barés, D Wang, D Wang, T Bertrand, CS O'Hern… - Physical Review E, 2017 - APS
We present the experimental and numerical studies of a two-dimensional sheared
amorphous material composed of bidisperse photoelastic disks. We analyze the statistics of …

Yielding of glass under shear: A directed percolation transition precedes shear-band formation

GP Shrivastav, P Chaudhuri, J Horbach - Physical Review E, 2016 - APS
Under external mechanical loading, glassy materials, ranging from soft matter systems to
metallic alloys, often respond via formation of inhomogeneous flow patterns, during yielding …

On the density of shear transformations in amorphous solids

J Lin, A Saade, E Lerner, A Rosso, M Wyart - Europhysics Letters, 2014 - iopscience.iop.org
We study the stability of amorphous solids, focussing on the distribution P (x) of the local
stress increase x that would lead to an instability. We argue that this distribution behaves as …

Creep and flow of glasses: strain response linked to the spatial distribution of dynamical heterogeneities

T Sentjabrskaja, P Chaudhuri, M Hermes, WCK Poon… - Scientific reports, 2015 - nature.com
Mechanical properties are of central importance to materials sciences, in particular if they
depend on external stimuli. Here we investigate the rheological response of amorphous …

Mean-field description of plastic flow in amorphous solids

J Lin, M Wyart - Physical review X, 2016 - APS
Failure and flow of amorphous materials are central to various phenomena including
earthquakes and landslides. There is accumulating evidence that the yielding transition …

Criticality in the approach to failure in amorphous solids

J Lin, T Gueudré, A Rosso, M Wyart - Physical review letters, 2015 - APS
