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 …

Modeling the mechanics of amorphous solids at different length scale and time scale

D Rodney, A Tanguy… - Modelling and Simulation …, 2011 - iopscience.iop.org
We review the recent literature on the simulation of the structure and deformation of
amorphous solids, including oxide and metallic glasses. We consider simulations at different …

Random critical point separates brittle and ductile yielding transitions in amorphous materials

M Ozawa, L Berthier, G Biroli… - Proceedings of the …, 2018 - National Acad Sciences
We combine an analytically solvable mean-field elasto-plastic model with molecular
dynamics simulations of a generic glass former to demonstrate that, depending on their …

Perspective: Supercooled liquids and glasses

MD Ediger, P Harrowell - The Journal of chemical physics, 2012 - pubs.aip.org
Supercooled liquids and glasses are important for current and developing technologies.
Here we provide perspective on recent progress in this field. The interpretation of …

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 …

How thermally activated deformation starts in metallic glass

Y Fan, T Iwashita, T Egami - Nature communications, 2014 - nature.com
The studies on dynamics and deformation in glassy materials are particularly challenging
because of their strongly disordered atomic structure. Here, by probing the changes in the …

Local elasticity map and plasticity in a model Lennard-Jones glass

M Tsamados, A Tanguy, C Goldenberg, JL Barrat - Physical Review E …, 2009 - APS
In this work we calculate the local elastic moduli in a weakly polydispersed two-dimensional
Lennard-Jones glass undergoing a quasistatic shear deformation at zero temperature. The …

Driving rate dependence of avalanche statistics and shapes at the yielding transition

C Liu, EE Ferrero, F Puosi, JL Barrat, K Martens - Physical review letters, 2016 - APS
We study stress time series caused by plastic avalanches in athermally sheared disordered
materials. Using particle-based simulations and a mesoscopic elastoplastic model, we …

A unified approach to model elasto-viscoplastic thixotropic yield-stress materials and apparent yield-stress fluids

PR de Souza Mendes, RL Thompson - Rheologica Acta, 2013 - Springer
A constitutive model for elasto-viscoplastic thixotropic materials is proposed. It consists of
two differential equations, one for the stress and the other for the structure parameter, a …

Encoding of memory in sheared amorphous solids

D Fiocco, G Foffi, S Sastry - Physical review letters, 2014 - APS
We show that memory can be encoded in a model amorphous solid subjected to athermal
oscillatory shear deformations, and in an analogous spin model with disordered interactions …
