从铝箔的随机和不可逆的紧凑型获得的皱纹表面（CS）是低密度分形结构，随着它们的尺寸增加，它们变得越来越容易变形。作者研究这些物体的变形时，提交给机械力。特别是，他们描述了八个缩放关系的行为，这些缩放关系连接了这些CS等量，例如应力，应变，表面粗糙度和几何变量。报告了从缩放关系中获得的关键指数以及有关这些过程中普遍行为存在的一些线索。
Crumpled surfaces (CS) obtained from random and irreversible compactification of aluminium foils are low-density fractal structures which become increasingly easy to deform as their size increases. The authors study the deformation of these objects when submitted to mechanical forces. In particular, they describe the behaviour of eight scaling relations which connect quantities such as stress, strain, surface roughness and geometrical variables for these CS. The critical exponents obtained from the scaling relations and some clues concerning the existence of universal behaviour in these processes are reported.
