Periodic Folding of Thin Sheets
SIAM Journal on Applied Mathematics, 1995Summary: When a thin sheet of a flexible material such as paper is fed from a horizontal spool towards a rough horizontal plane below it, the sheet folds on itself in a regular manner. We model this phenomenon as a free boundary problem for a nonlinear elastic sheet, taking into account the stiffness and weight of the sheet, and the height of the spool

Designing and programming self-folding sheets
Robotics and Autonomous Systems, 2014Abstract This paper considers a robot in the form of a self-folding sheet that is capable of origami-style autonomous folding. The sheet is composed of triangular tiles, folding actuators and an integrated electronic substrate, and is formed as an n × m box-pleated crease pattern.

Delineation of Folding Pathways of a β-Sheet Miniprotein
The Journal of Physical Chemistry B, 2011Several methods have been developed in the past few years for the analysis of molecular dynamics simulations of biological (macro)molecules whose complexity is difficult to capture by simple projections of the free-energy surface onto one or two geometric variables.

Folding of viscous sheets and filaments
Europhysics Letters (EPL), 2000We consider the nonlinear folding behavior of a viscous filament or a sheet under the influence of an external force such as gravity. Everyday examples of this phenomenon are provided by the periodic folding of a sheet of honey as it impinges on toast, or the folding of a stream of shampoo as it falls on one's hand.

Current Opinion in Structural Biology, 1995
Abstract In the past year, interesting new information concerning various aspects of the folding process of β-sheet proteins has been gleaned. Kinetic and equilibrium folding intermediates have been characterized. Studies of extensively denatured states and of model peptide fragments have enabled important steps to be taken towards an understanding ...

Folding in the Greenland Ice Sheet
Journal of Geophysical Research: Solid Earth, 1987The deformation of layering into folds is modeled for a linear viscous medium moving over a décollement. Folds are generated by flow variations caused by relief on the décollement, variations in friction, or both. The model is applied to folds forming now in the Greenland Ice Sheet near Dye 3, for which more complete data are available than for ...

Nano Letters, 2016
Focused ion beams (FIBs) are versatile tools with cross-disciplinary applications from the physical and life sciences to archeology. Nevertheless, the nanoscale patterning precision of FIBs is often accompanied by defect formation and sample deformation.

The folding of heavy fabric sheets
International Journal of Mechanical Sciences, 1978Abstract An example of a fabric folding under its own weight is analysed, using bending curve theory to model the fabric cross-section. Reduction of the governing differential equations, and the boundary conditions appropriate to each stage of the motion, to dimensionless form reveals that the parameters which characterize the deformed state depend ...

Scaling properties of randomly folded plastic sheets
Physical Review E, 2007We study the scaling properties of randomly folded aluminum sheets of different thicknesses h and widths L . We found that the fractal dimension D=2.30+/-0.01 and the force scaling exponent delta=0.21+/-0.02 are independent of the sheet thickness and close to those obtained in numerical simulations with a coarse-grained model of triangulated self ...
