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

Ductile and brittle yielding in thermal and athermal amorphous materials

HJ Barlow, JO Cochran, SM Fielding - Physical Review Letters, 2020 - APS
We study theoretically the yielding of sheared amorphous materials as a function of
increasing levels of initial sample annealing prior to shear, in three widely used constitutive …

Yielding is an absorbing phase transition with vanishing critical fluctuations

T Jocteur, S Figueiredo, K Martens, E Bertin, R Mari - Physical Review Letters, 2024 - APS
The yielding transition in athermal complex fluids can be interpreted as an absorbing phase
transition between an elastic, absorbing state with high mesoscopic degeneracy and a …

Transforming mesoscale granular plasticity through particle shape

KA Murphy, KA Dahmen, HM Jaeger - Physical Review X, 2019 - APS
When an amorphous material is strained beyond the point of yielding, it enters a state of
continual reconfiguration via dissipative, avalanchelike slip events that relieve built-up local …

Elastoplastic description of sudden failure in athermal amorphous materials during quasistatic loading

M Popović, TWJ de Geus, M Wyart - Physical Review E, 2018 - APS
The response of amorphous materials to an applied strain can be continuous or instead
discontinuous if the initial configuration is very stable. We study theoretically how such a …

Finite-disorder critical point in the yielding transition of elastoplastic models

S Rossi, G Biroli, M Ozawa, G Tarjus, F Zamponi - Physical Review Letters, 2022 - APS
Upon loading, amorphous solids can exhibit brittle yielding, with the abrupt formation of
macroscopic shear bands leading to fracture, or ductile yielding, with a multitude of plastic …
