Crackling dynamics in material failure as the signature of a self-organized dynamic phase transition
Daniel Bonamy, Stéphane Santucci, Laurent Ponson
We derive here a linear elastic stochastic description for slow crack growth in heterogeneous materials. This approach succeeds in reproducing quantitatively the intermittent crack…
Cleaved surface of i-AlPdMn quasicrystals: Influence of the local temperature elevation at the crack tip on the fracture surface roughness
Laurent Ponson, Daniel Bonamy, Luc Barbier
Roughness of i-AlPdMn cleaved surfaces are presently analysed. From the atomic scale to 2-3 nm, they are shown to exhibit scaling properties hiding the cluster (0.45 nm) aperiodic…
Nanoscale damage during fracture in silica glass
Daniel Bonamy, Silke Prades, Cindy Rountree +5
We report here atomic force microscopy experiments designed to uncover the nature of failure mechanisms occuring within the process zone at the tip of a crack propagating into a si…
Two-dimensional scaling properties of experimental fracture surfaces
Laurent Ponson, Daniel Bonamy, Elisabeth Bouchaud
The morphology of fracture surfaces encodes the various complex damage and fracture processes occurring at the microstructure scale that have lead to the failure of a given heterog…
