Wrapping and unwrapping multifractal fields: Application to fatigue and abrupt failure fracture surfaces by Samy Lakhal, Laurent Ponson, Michael Benzaquen, Jean-Philippe Bouchaud

“…Such construction procedure is then used in d=2 to “unwrap” experimental fracture surfaces of an aluminum alloy obtained by abrupt and fatigue failure. Our analysis demonstrates the presence of anisotropic and filamental structures, ascribed to the dissipative nature of the damage mechanisms that underlie material failure.…”
