Elastic interactions of plastic events in strained amorphous solids before yield

J Duan, YJ Wang, LH Dai, MQ Jiang - Physical Review Materials, 2023 - APS
It has been widely accepted that the plastic events of amorphous solids after mechanical
yield belong to a highly correlated avalanche state. However, whether the plastic events …

Structural relaxation affecting shear-transformation avalanches in metallic glasses

T Niiyama, M Wakeda, T Shimokawa, S Ogata - Physical Review E, 2019 - APS

Distinct avalanche dynamics detected in metallic glasses with high energy state revealing the crack-like shear banding mechanism

K Tao, F Li, Y Liu, E Pineda, K Song, J Qiao - International Journal of …, 2024 - Elsevier
When a sufficiently high stress is applied to a metallic glass, causing plastic deformation, the
material undergoes structural reconfiguration through dissipative slip avalanche events that …

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

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 …

Self-organized intermittent plastic flow in bulk metallic glasses

G Wang, KC Chan, L Xia, P Yu, J Shen, WH Wang - Acta Materialia, 2009 - Elsevier

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 …
