We study the effect of folding ridges on the scaling properties of randomly crumpled sheets of different kinds of paper in the folded and unfolded states. We found that the mean ridge length scales with the sheet size with the scaling exponent mu determined by the competition between bending and stretching deformations in the folded sheet. This scaling determines the mass fractal dimension of randomly folded balls D{M}=2/mu. We also found that surfaces of crumpled balls, as well as unfolded…

Fractal Geometry and Mechanics of Randomly Folded Thin Sheets

This work is devoted to the statistical geometry of crumpling network and its effect on the geometry and mechanical properties of randomly folded materials. We found that crumpling networks in…

Power law scaling of lateral deformations with universal Poisson's index for randomly folded thin sheets

We study the lateral deformations of randomly folded elastoplastic and predominantly plastic thin sheets under the uniaxial and radial compressions. We found that the lateral deformations of…

The effect of plasticity in crumpling of thin sheets.

A numerical model that can be purely elastic or elasto-plastic is introduced and evidence is found of Dpl not being universal but dependent on the plastic yield point of the material.

Entropic rigidity of a crumpling network in a randomly folded thin sheet.

An explicit force-compression relationship is derived which precisely fits the experimental data for randomly folded matter and indicates that the entropic rigidity modulus scales as the power of the mass density of the folded ball with universal scaling exponent.

A model for the fragmentation kinetics of crumpled thin sheets

A physical model for the evolution of facet area and ridge length distributions of crumpled sheets is identified, and a mechanism for re-fragmentation driven by geometric frustration is proposed, which establishes a feedback loop in which the facet size distribution informs the subsequent rate of fragmentation under repeated confinement.

Topological crossovers in the forced folding of self-avoiding matter

Fractal features of a crumpling network in randomly folded thin matter and mechanics of sheet crushing.

It is stated that self-avoiding interactions introduce a characteristic length scale of sheet crumpling.

Statistics of energy dissipation and stress relaxation in a crumpling network of randomly folded aluminum foils.

It is argued that the dissipation of elastic energy in crushed aluminum foils is ruled by a multiplicative Poisson process governed by the maximum waiting time distribution.

Crumpling of thin sheets as a basis for creating mechanical metamaterials

Crumpled thin sheets exhibit extraordinary characteristics such as a high strength combined with a low volume ratio. This review focuses on the physics of crumpled thin sheets, including the…
