Exploring the scales in highly deformable grain assemblies when compressed far beyond the jammed state
Résumé
When hard grains (i.e., with high stiffness relatively to the applied stress) are compressed inside a box, they tend to rearrange themselves in a more compact way until a permanent contact forces network is reached, meaning the end of the compression. This “jammed state” depends on the morphology of the grain and the inter-grain friction. What happens now if we consider grains that can deform when the applied stress becomes significant? The compression continues beyond the jammed state, mainly due to the change in shape of the grains and, to a lesser extent, due to their rearrangements. As a result, the solid fraction exceeds that of the Random Close Packing, and it would even be possible to en
