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 …

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 …

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 …

Statistical physics of elastoplastic steady states in amorphous solids: Finite temperatures and strain rates

S Karmakar, E Lerner, I Procaccia, J Zylberg - Physical Review E—Statistical …, 2010 - APS
The effect of finite temperature T and finite strain rate γ ̇ on the statistical physics of plastic
deformations in amorphous solids made of N particles is investigated. We recognize three …

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 …

Mechanical yield in amorphous solids: A first-order phase transition

PK Jaiswal, I Procaccia, C Rainone, M Singh - Physical review letters, 2016 - APS
Amorphous solids yield at a critical value of the strain (in strain-controlled experiments); for
larger strains, the average stress can no longer increase—the system displays an …

Avalanches, precursors, and finite-size fluctuations in a mesoscopic model of amorphous plasticity

M Talamali, V Petäjä, D Vandembroucq, S Roux - Physical Review E …, 2011 - APS
We discuss avalanche and finite-size fluctuations in a mesoscopic model to describe the
shear plasticity of amorphous materials. Plastic deformation is assumed to occur through …

Universality of the plastic instability in strained amorphous solids

R Dasgupta, S Karmakar, I Procaccia - Physical review letters, 2012 - APS
By comparing the response to external strains in metallic glasses and in Lennard-Jones
glasses we find a quantitative universality of the fundamental plastic instabilities in the …

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 …

Local yield stress statistics in model amorphous solids

A Barbot, M Lerbinger, A Hernandez-Garcia… - Physical Review E, 2018 - APS
We develop and extend a method presented by Patinet, Vandembroucq, and Falk [Phys.
Rev. Lett. 117, 045501 (2016) PRLTAO 0031-9007 10.1103/PhysRevLett. 117.045501] to …
