Hoop compression driven instabilities in spontaneously formed multilayer graphene blisters over a polymeric substrate

M Pandey, R Ahuja, R Kumar - Nanotechnology, 2023 - iopscience.iop.org
The blistering of elastic membranes is prone to elastic-solid as well as substrate-based
mechanical instabilities. The solid-based instabilities have been well-explored in the …

[HTML][HTML] Wrinkle, fold, and ridge patterns of thin films attached to a compliant substrate: Direct numerical simulations involving plastic yielding

S Nikravesh, YL Shen - Thin-Walled Structures, 2024 - Elsevier
Surface wrinkling is a frequently observed form of deformation instability when a thin film
bonded to a compliant substrate is under in-plane compression. In this study, a recently …

Delamination from an adhesive sphere: Curvature-induced dewetting versus buckling

Everyday experience confirms the tendency of adhesive films to detach from spheroidal
regions of rigid substrates—what is a petty frustration when placing a sticky band aid onto a …

Plasticity-mediated deformation instabilities in thin film-compliant substrate systems: direct three-dimensional simulations

S Nikravesh, YL Shen - Journal of Materials Science, 2024 - Springer
Surface wrinkles driven by mechanical instability commonly form in thin-film structures
attached to a compliant substrate. In this study, a recently developed computational …

Surface instability, termed wrinkling, might occur in compressed bilayer systems constituted
by an external rigid skin resting on an internal soft substrate, where wrinkling is favored by …

Coexistence and Coevolution of Wrinkle and Ridge Patterns in the Film–Substrate System by Uniaxial Compression

S Yu, J Zhang, H Zhou, Y Sun, Y Ni - Langmuir, 2023 - ACS Publications
Homogeneous wrinkles and localized patterns are ubiquitous in nature and are useful for a
wide range of practical applications. Although various strain-driven surface instability modes …

Ridge localization driven by wrinkle packets

X Guan, N Nguyen, E Cerda, L Pocivavsek… - Soft Matter, 2023 - pubs.rsc.org
While buckling is a time independent phenomenon for filaments or films bonded to soft
elastic substrates, time evolution plays an important role when the substrate is a viscous …

Fluttering-induced flow in a closed chamber

K Goncharuk, Y Feldman, O Oshri - Journal of Fluid Mechanics, 2023 - cambridge.org
We study the emergence of fluid flow in a closed chamber that is driven by dynamical
