Athermal quasistatic cavitation in amorphous solids: Effect of random pinning

UA Dattani, S Karmakar, P Chaudhuri - The Journal of Chemical …, 2023 - pubs.aip.org
Amorphous solids are known to fail catastrophically via fracture, and cavitation at nano-
metric scales is known to play a significant role in such a failure process. Micro-alloying via …

Pinning effect on the correlations of nonaffine displacement in metallic glasses

Y Liu, H Liu, H Peng - Journal of Non-Crystalline Solids, 2023 - Elsevier
We mimic the structural heterogeneity of inclusions in nanoscale by pinning a portion of
atoms in CuZr metallic glasses (MGs) on molecular dynamics simulations with shear …

Effect of pinning on shear banding in metallic glasses

Y Liu, Z Yan, H Liu, B Shang, H Peng - Physical Review B, 2024 - APS
Unveiling the ingredients that can operate shear bands is a cardinal task to tailor the
mechanical properties of metallic glasses. Yet the effect of heterogeneous inclusions on …

Finite-dimensional signature of spinodal instability in an athermal hysteretic transition

A Banerjee, T Bar - Physical Review B, 2023 - APS
We study the off-equilibrium critical phenomena across a hysteretic first-order transition in
disordered athermal systems. The study focuses on the zero temperature random field Ising …

Suppression of spinodal instability by disorder in an athermal system

T Bar, A Ghosh, A Banerjee - Physical Review B, 2021 - APS
We observed asymmetric critical slowing down and asymmetric dynamical scaling exponent
in the superheating and supercooling kinetic processes during the thermally-induced metal …

Absorbing-state transitions in particulate systems under spatially varying driving

BP Bhowmik, C Ness - arXiv preprint arXiv:2403.02487, 2024 - arxiv.org
We study the absorbing state transition in particulate systems under spatially
inhomogeneous driving using a modified random organization model. For smoothly varying …

Yielding transition of amorphous solids in the presence of aspherical impurities

A Mutneja, BP Bhowmik, S Karmakar - arXiv preprint arXiv:2307.01002, 2023 - arxiv.org
Understanding the mechanical properties of amorphous solids has been a field of intense
research not only for the zoo of interesting phenomena one observes once these solids are …

Mechanical behaviour of glasses and amorphous materials

ADS Parmar, S Sastry - Advances in the Chemistry and Physics of …, 2020 - World Scientific
A wide range of materials can exist in microscopically disordered solid forms, referred to as
amorphous solids or glasses. Such materials–oxide glasses and metallic glasses, to …
