MECHANICALLY DEFORMED CRUMPLED SURFACES

Crumpled surfaces (CS) obtained from random and irreversible compactification of aluminum foils are low-density fractal structures which become increasingly easy to deform as their size increases. In this work we study the deformation of these objects when submitted to mechanical forces. In particular, we describe the behaviour of eight scaling relations which connect quantities 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.
