Folding a strip of paper generates extremely localised plastic strains. The relaxation of the residual stresses results in a ridge that joins two flat faces at an angle known as the dihedral angle. When constrained isostatically, the strip will be at its undeformed roof-like state. Instead, if confined hyperstatically, the flat faces will undergo bending. We demonstrate that the generated curvatures can change their sign with appropriate rotations applied at the ends. We use Euler’s theory of… Expand

Bistability and equilibria of creased annular sheets and strips
A creased thin disk is generally bistable since the crease could be pushed through to form a stable cone-like inverted state with an elastic singularity corresponding to the vertex of the conicalExpand

Snap-buckling in asymmetrically constrained elastic strips.
TLDR
This work studies snap-buckling of an elastic strip with one end hinged and the other end clamped, which breaks the intrinsic symmetry of the strip, generating mechanical behaviors, including largely hysteretic but reproduced force responses and switchlike discontinuous shape changes. Expand
Bifurcations of buckled , clamped anisotropic rods and thin bands under lateral end translations
Motivated by observations of snap-through phenomena in buckled elastic strips subject to clamping and lateral end translations, we experimentally explore the multi-stability and bifurcations of thinExpand
A meshless method for the nonlinear von Kármán plate with multiple folds of complex shape
We present a meshless discretisation method for the solution of the non-linear equations of the von Kármán plate containing folds. The plate has Mindlin–Reissner kinematics where the rotations areExpand
Confining Thin Elastic Sheets and Folding Paper
Crumpling a sheet of paper leads to the formation of complex folding patterns over several length scales. This can be understood on the basis of the interplay of a nonconvex elastic energy, whichExpand
Local mechanical description of an elastic fold.
TLDR
An elastic model of the fold is built upon a continuous description of both the faces and the crease as a thin sheet with a non-flat reference configuration that yields the local fold properties and explains the significant differences between tensile and compression regimes. Expand
Mechanics of wrinkle/ridge transitions in thin film/substrate systems
Abstract The mechanics of the formation and propagation of ridges on compressed stiff film/compliant substrate systems is studied theoretically and experimentally. Ridges form on bilayer systemsExpand
Draping films: a wrinkle to fold transition.
TLDR
In this Letter, the deformation of an axisymmetric sheet is examined and the force required to generate a fold is quantified, observing that the energy of formation for a single fold scales nearly linearly with the film thickness. Expand
Postbuckling behavior of variable-arc-length elastica connected with a rotational spring joint including the effect of configurational force
This paper aims to study the behavior of a variable-arc-length (VAL) elastica subjected to the end loading, where a rotational spring joint is placed within the span length of the elastica. One endExpand
Snapping of elastic strips with controlled ends
Abstract Snapping mechanisms are investigated for an elastic strip with ends imposed to move and rotate in time. Attacking the problem analytically via Euler’s elastica and the second variation ofExpand
Mechanical response of a creased sheet.
TLDR
It is shown that a characteristic length scale, defined by the ratio of bending to hinge energies, governs whether the structure's response consists in angle opening or panel bending when a small load is applied. Expand
