Fluid lipid membranes: From differential geometry to curvature stresses

M Deserno - Chemistry and physics of lipids, 2015 - Elsevier
A fluid lipid membrane transmits stresses and torques that are fully determined by its
geometry. They can be described by a stress-and torque-tensor, respectively, which yield …

Shape transitions in hyperbolic non-Euclidean plates

J Gemmer, SC Venkataramani - Soft Matter, 2013 - pubs.rsc.org
A non-Euclidean plate is a thin elastic object whose intrinsic geometry is not flat and hence
has residual stresses arising from being embedded in three dimensional space. Recently …

Equilibrium shapes with stress localisation for inextensible elastic Möbius and other strips

EL Starostin, GHM van der Heijden - Journal of Elasticity, 2015 - Springer
We formulate the problem of finding equilibrium shapes of a thin inextensible elastic strip,
developing further our previous work on the Möbius strip. By using the isometric nature of …

Confinement of semiflexible polymers

J Guven, P Vázquez-Montejo - Physical Review E—Statistical, Nonlinear, and …, 2012 - APS
A variational framework is developed to examine the equilibrium states of a semiflexible
polymer that is constrained to lie on a fixed surface. As an application the confinement of a …

Paramagnetic filaments in a fast precessing field: Planar versus helical conformations

P Vázquez-Montejo, JM Dempster, MO de la Cruz - Physical Review Materials, 2017 - APS
We examine analytically equilibrium conformations of elastic chains of paramagnetic beads
in the presence of a precessing magnetic field. Conformations of these filaments are …

Foldable cones as a framework for nonrigid origami

I Andrade-Silva, M Adda-Bedia, MA Dias - Physical Review E, 2019 - APS
The study of origami-based mechanical metamaterials usually focuses on the kinematics of
deployable structures made of an assembly of rigid flat plates connected by hinges. When …

On local kirigami mechanics I: Isometric conical solutions

S Sadik, MA Dias - Journal of the Mechanics and Physics of Solids, 2021 - Elsevier
Over the past decade, kirigami—the Japanese art of paper cutting—has been playing an
increasing role in the emerging field of mechanical metamaterials and a myriad of other …

The geometry of fluid membranes: Variational principles, symmetries and conservation laws

J Guven, P Vázquez-Montejo - The Role of Mechanics in the Study of Lipid …, 2018 - Springer
The behavior of a lipid membrane on mesoscopic scales is captured unusually accurately by
its geometrical degrees of freedom. Indeed, the membrane geometry is, very often, a direct …

Strain tensor selection and the elastic theory of incompatible thin sheets

O Oshri, H Diamant - Physical Review E, 2017 - APS
The existing theory of incompatible elastic sheets uses the deviation of the surface metric
from a reference metric to define the strain tensor [Efrati, J. Mech. Phys. Solids 57, 762 …

Confined disclinations: Exterior versus material constraints in developable thin elastic sheets

E Efrati, L Pocivavsek, R Meza, KYC Lee, TA Witten - Physical Review E, 2015 - APS
We examine the shape change of a thin disk with an inserted wedge of material when it is
pushed against a plane, using analytical, numerical, and experimental methods. Such …
