Homoclinic orbits in reversible systems and their applications in mechanics, fluids and optics

AR Champneys - Physica D: Nonlinear Phenomena, 1998 - Elsevier
This survey article reviews the theory and application of homoclinic orbits to equilibria in
reversible continuous-time dynamical systems, where the homoclinic orbit and the …

Wrinkle to fold transition: influence of the substrate response

F Brau, P Damman, H Diamant, TA Witten - Soft Matter, 2013 - pubs.rsc.org
Spatially confined rigid membranes reorganize their morphology in response to imposed
constraints. Slight compression of a rigid membrane resting on a soft foundation creates a …

Cellular buckling in long structures

GW Hunt, MA Peletier, AR Champneys, PD Woods… - Nonlinear …, 2000 - Springer
A long structural system with an unstable (subcritical) post-buckling response that
subsequently restabilizes typically deformsin a cellular manner, with localized buckles first …

Emergence of active nematics in chaining bacterial biofilms

YI Yaman, E Demir, R Vetter, A Kocabas - Nature communications, 2019 - nature.com
Growing tissue and bacterial colonies are active matter systems where cell divisions and
cellular motion generate active stress. Although they operate in the non-equilibrium regime …

Compression induced folding of a sheet: An integrable system

H Diamant, TA Witten - Physical review letters, 2011 - APS
The apparently intractable shape of a fold in a compressed elastic film lying on a fluid
substrate is found to have an exact solution. Such systems buckle at a nonzero wave vector …

Nonlinear stability analysis of pre-stressed elastic bodies

YB Fu, RW Ogden - Continuum Mechanics and Thermodynamics, 1999 - Springer
This article is concerned with the nonlinear analysis of the stability of thick elastic bodies
subjected to finite elastic deformations. The analysis is based on the theory of small elastic …

Localization in spherical shell buckling

B Audoly, JW Hutchinson - Journal of the Mechanics and Physics of Solids, 2020 - Elsevier
This paper addresses localization of the deformation due to buckling that occurs
immediately following the onset of bifurcation in the axisymmetric buckling of a perfect …

Buckling of paramagnetic chains in soft gels

S Huang, G Pessot, P Cremer, R Weeber, C Holm… - Soft Matter, 2016 - pubs.rsc.org
We study the magneto-elastic coupling behavior of paramagnetic chains in soft polymer gels
exposed to external magnetic fields. To this end, a laser scanning confocal microscope is …

Wrapping liquids, solids, and gases in thin sheets

JD Paulsen - Annual Review of Condensed Matter Physics, 2019 - annualreviews.org
Many objects in nature and industry are wrapped in a thin sheet to enhance their chemical,
mechanical, or optical properties. Similarly, there are a variety of methods for wrapping, from …

Wrinkles and folds in a fluid-supported sheet of finite size

O Oshri, F Brau, H Diamant - Physical Review E, 2015 - APS
A laterally confined thin elastic sheet lying on a liquid substrate displays regular undulations,
called wrinkles, characterized by a spatially extended energy distribution and a well-defined …
