A pressure chamber is designed to study the crumpling process under an ambient force. The compression force and its resulting radius for the ball obey a power law with an exponent that is independent of the thickness and initial size of the sheet. However, the exponent is found to be material dependent and less than the universal value, 0.25, claimed by the previous simulations. The power-law behavior disappears at high pressure when the compressibility drops discontinuously, which is… 

Figures and Topics from this paper

Effect of the material properties on the crumpling of a thin sheet.
TLDR
This work studies the effect of plasticity on the crumpling of sheets of different materials by performing isotropic compaction experiments onsheet of different sizes and elasto-plastic properties, and quantifies the material properties using a dimensionless foldability index.
Stress defocusing in anisotropic compaction of thin sheets.
TLDR
As compaction proceeds, it is found that sheets first develop singular folds involving ridges or developable cones, but eventually turn to regular folds free of any geometrical singularities, without ever having entered the plastic regime.
Orientational ordering in crumpled elastic sheets
We report an experimental study of the development of orientational order in a crumpled sheet, with a particular focus on the role played by the geometry of confinement. Our experiments are performed
The compressive strength of crumpled matter
TLDR
It is shown that it is the bending in ridges making both elastic and plastic sheets resistant to compression and described the mechanical response using an empirical model.
Slow dynamics of stress and strain relaxation in randomly crumpled elasto-plastic sheets.
TLDR
The findings suggest that, in an axially compressed ball folded from an elastic or elasto-plastic material, the relaxation dynamics is ruled by activated processes of an energy foci rearrangement in the crumpling network.
Statistics of energy dissipation and stress relaxation in a crumpling network of randomly folded aluminum foils.
TLDR
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.
Direct observation of the temporal and spatial dynamics during crumpling.
TLDR
Direct measurements of the configurations of a fully elastic sheet evolving during the dynamic process of crumpling under isotropic confinement are presented and the formation of a network of ridges and vertices into which the energy is localized is observed.
Fractal features of a crumpling network in randomly folded thin matter and mechanics of sheet crushing.
TLDR
It is stated that self-avoiding interactions introduce a characteristic length scale of sheet crumpling.
Mechanical properties and relaxation behavior of crumpled aluminum foils
Crumpled metal foils are a new type of lightweight cellular materials. The engineering applications of crumpled foils require a deep understanding of their response to mechanical loads. In order to
Effect of ridge-ridge interactions in crumpled thin sheets.
TLDR
Whether and how the energy scaling based on the single-ridge approximation is revised in an actual crumpled sheet is studied, namely, in the presence of ridge-ridge interactions, to verify the existence of a scaling relation that is more general than the familiar power law at covering the whole density range.
