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 …

Elastic avalanches reveal marginal behavior in amorphous solids

B Shang, P Guan, JL Barrat - Proceedings of the National …, 2020 - National Acad Sciences
Mechanical deformation of amorphous solids can be described as consisting of an elastic
part in which the stress increases linearly with strain, up to a yield point at which the solid …

Brittle yielding of amorphous solids at finite shear rates

M Singh, M Ozawa, L Berthier - Physical Review Materials, 2020 - APS
Amorphous solids display a ductile to brittle transition as the kinetic stability of the quiescent
glass is increased, which leads to a material failure controlled by the sudden emergence of …

Criticality in the approach to failure in amorphous solids

J Lin, T Gueudré, A Rosso, M Wyart - Physical review letters, 2015 - APS
Failure of amorphous solids is fundamental to various phenomena, including landslides and
earthquakes. Recent experiments indicate that highly plastic regions form elongated …

Statistical physics of the yielding transition in amorphous solids

S Karmakar, E Lerner, I Procaccia - … Review E—Statistical, Nonlinear, and Soft …, 2010 - APS
The art of making structural, polymeric, and metallic glasses is rapidly developing with many
applications. A limitation is that under increasing external strain all amorphous solids (like …

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 …

The yielding transition in amorphous solids under oscillatory shear deformation

P Leishangthem, ADS Parmar, S Sastry - Nature communications, 2017 - nature.com
Amorphous solids are ubiquitous among natural and man-made materials. Often used as
structural materials for their attractive mechanical properties, their utility depends critically on …

Avalanches in strained amorphous solids: Does inertia destroy critical behavior?

KM Salerno, CE Maloney, MO Robbins - Physical Review Letters, 2012 - APS
Simulations are used to determine the effect of inertia on athermal shear of amorphous two-
dimensional solids. In the quasistatic limit, shear occurs through a series of rapid …

Predicting plastic flow events in athermal shear-strained amorphous solids

S Karmakar, A Lemaitre, E Lerner, I Procaccia - Physical review letters, 2010 - APS
We propose a method to predict the value of the external strain where a generic amorphous
solid will fail by a plastic response (ie, an irreversible deformation), solely on the basis of …

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 …
