Energy distributions and effective temperatures in the packing of elastic sheets

Résumé

The packing of elastic sheets is investigated in a quasi two-dimensional experimental setup: a sheet is pulled through a rigid hole acting as a container, so that its configuration is mostly prescribed by the cross-section of the sheet in the plane of the hole. The geometrical properties and energies of the branches forming the cross-section are broadly distributed. The distributions of energy have exponential tails yielding effective temperatures. Two sub-systems can be defined: in contact with the container and within the bulk. While the geometrical properties differ between the sub-systems, their energy distributions are identical, indicating that 'thermal equilibration' occurs.
