      abstract     = {Thin elastic sheets are important materials across length
                      scales ranging from mesoscopic (polymerized membranes, clay
                      platelets, virus capsids) to macroscopic (paper, metal
                      foils). The crumpling of such sheets by external forces is
                      characterized by the formation of a complex pattern of
                      folds. We have investigated the role of self-avoidance, the
                      fact that the sheets cannot self-intersect, for the
                      crumpling process by large-scale computer simulations. At
                      moderate compression, the force-compression relations of
                      crumpled sheets for both self-avoiding and phantom sheets
                      are found to obey universal power-law behaviours. However,
                      self-avoiding sheets are much stiffer than phantom sheets
                      and, for a given compression, develop many more folds.
                      Moreover, self-avoidance is relevant already at very small
                      volume fractions. The fold-length distribution for crumpled
                      sheets is determined, and is found to be well-described by a
                      log-normal distribution. The stiffening owing to
                      self-avoidance is reflected in the changing nature of the
                      sheet-to-sheet contacts from line-like to two-dimensionally
                      extended with increasing compression.},
