Elastic fluctuations and structural heterogeneities in metallic glasses

C Liu, R Maaß - Advanced Functional Materials, 2018 - Wiley Online Library
Suppressing crystallization of a metallic melt results in a disordered solid, also known as a
metallic glass. One may conclude that a metallic glass is free of defined structural length …

Identifying microscopic factors that influence ductility in disordered solids

H ** between atomistic and elasto-plastic models
DF Castellanos, S Roux, S Patinet - Acta Materialia, 2022 - Elsevier
Mesoscale elasto-plastic models, with statistically distributed structural properties and elastic
coupling between discrete blocks, have been shown to quantitatively reproduce the main …

Data-driven surrogates for high dimensional models using Gaussian process regression on the Grassmann manifold

DG Giovanis, MD Shields - Computer Methods in Applied Mechanics and …, 2020 - Elsevier
This paper introduces a surrogate modeling scheme based on Grassmannian manifold
learning to be used for cost-efficient predictions of high-dimensional stochastic systems. The …

Rejuvenation and shear banding in model amorphous solids

A Barbot, M Lerbinger, A Lemaitre, D Vandembroucq… - Physical Review E, 2020 - APS
We measure the local yield stress, at the scale of small atomic regions, in a deeply
quenched two-dimensional glass model undergoing shear banding in response to athermal …

Elastoplastic approach based on microscopic insights for the steady state and transient dynamics of sheared disordered solids

C Liu, S Dutta, P Chaudhuri, K Martens - Physical Review Letters, 2021 - APS
We develop a framework to study the mechanical response of athermal amorphous solids
via a coupling of mesoscale and microscopic models. Using measurements of coarse …
