Periodic folding of a falling viscoelastic sheet
Physical Review E, 2020A viscoelastic solid sheet fed from a certain height towards a rigid horizontal plane folds on itself provided that there is no slip. This phenomenon commonly occurs in the manufacturing process of textile and paper products. In this paper we apply a particle dynamics model to investigate this phenomenon.

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.

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 ...

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 ...

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.
