22 Jun 2007 | Journal: | Phys Rev Lett, 98 (25), 255502 | 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 [J. Delour, J. F. Muzy, and A. Arneodo, Eur. Phys. J. B 23, 243 (2001)10.1007/s100510170074]. Using a large data set (102 fronts), we find a significant difference in local roughness between the slow (subcritical) and the fast growth regime. | Source: | PubMed, pmid17678036 | Services: | Forum | Review | Favorites |
