Mean-field theory of yielding under oscillatory shear

JT Parley, S Sastry, P Sollich - Physical Review Letters, 2022 - APS
We study a mean field elastoplastic model, embedded within a disordered landscape of
local yield barriers, to shed light on the behavior of athermal amorphous solids subject to …

Mapping out the glassy landscape of a mesoscopic elastoplastic model

D Kumar, S Patinet, CE Maloney, I Regev… - The Journal of …, 2022 - pubs.aip.org
We develop a mesoscopic model to study the plastic behavior of an amorphous material
under cyclic loading. The model is depinning-like and driven by a disordered thresholds …

[HTML][HTML] Fatigue fracture mechanism of amorphous materials from a density-based coarse-grained model

Y Kurotani, H Tanaka - Communications Materials, 2022 - nature.com
Fatigue fracture is a unique failure mode of materials induced by repeated loading and is
crucial for the long-term stability of materials used in cars and aeroplanes. Fatigue is the …

Avalanches, clusters, and structural change in cyclically sheared silica glass

H Bhaumik, G Foffi, S Sastry - Physical Review Letters, 2022 - APS
We investigate avalanches and clusters associated with plastic rearrangements and the
nature of structural change in the prototypical strong glass, silica, computationally. We …

Loss of memory of an elastic line on its way to limit cycles

E Agoritsas, J Barés - Physical Review E, 2024 - APS
Oscillatory-driven amorphous materials forget their initial configuration and converge to limit
cycles. Here we investigate this memory loss under a nonquasistatic drive in a minimal …

Slow fatigue and highly delayed yielding via shear banding in oscillatory shear

JO Cochran, GL Callaghan, MJG Caven… - Physical Review Letters, 2024 - APS
We study theoretically the dynamical process of yielding in cyclically sheared amorphous
materials, within a thermal elastoplastic model and the soft glassy rheology model. Within …

Yielding transition of a two dimensional glass former under athermal cyclic shear deformation

H Bhaumik, G Foffi, S Sastry - The Journal of Chemical Physics, 2022 - pubs.aip.org
We study numerically the yielding transition of a two dimensional model glass subjected to
athermal quasi-static cyclic shear deformation, with the aim of investigating the effect on the …

The effect of forced vibration coupling on amorphous alloy superplasticity

XC Tang, XH Yao - Journal of Non-Crystalline Solids, 2024 - Elsevier
Vibration is a common phenomenon in nature and industry. While it typically appears as
damaging resonance that must be eliminated, it can also manifest as a novel technique …
