Description
Runze Liang and others show that smaller crumpled sheets carry loads more strongly in a 2026 study of atom-thin big molecules. Atom-thin stuff crumples into tangled shapes, and the mechanics of those crumpled states mark a new field.
Coarse-grained sims showed a broad reverse size effect: smaller sheets formed dense ridge webs with little self-folding, enabling swift load transfer, with a steady ridge-to-vertex gain ratio of 1.5 during packing. Tests on paper, aluminum foil, silicone, and rubber proved the effect across scales and stuffs. Engineers gain a size rule for designing crumpled guard stuffs.
