Discrepancy between sub-critical and fast rupture roughness : a cumulant analysis

Abstract : Rough crack fronts in a sheet of paper, obtained during a creep experiment, do not follow true scaling laws. Local roughness exponents are estimated using the first order cumulant, a quantity recently introduced in the turbulence literature. Using a large data set (102 fronts), we find a significant difference in local roughness between the slow (sub-critical) and the fast growth regime.
