Abstract

We study the roughness of randomly crumpled elastic sheets. Based on analytical and numerical calculations, we find that they are self affine with a roughness exponent equal to one. Such crumpling occurs e.g.\/ when wet paper dries. We also discuss the case of correlated crumpling, which occurs in connection with flattening of randomly folded paper.
