Atomic-scale avalanche along a dislocation in a random alloy
Sylvain Patinet, Daniel Bonamy, L Proville
The propagation of dislocations in random crystals is evidenced to be governed by atomic-scale avalanches whose the extension in space and the time intermittency characterizingly d…
Effect of the porosity on the fracture surface roughness of sintered materials: From anisotropic to isotropic self-affine scaling
Tristan Cambonie, Jonathan Bares, Lamine Hattali +3
To unravel how the microstructure affects the fracture surface roughness in heterogeneous brittle solids like rocks or ceramics, we characterized the roughness statistics of post-m…
Damage mechanisms in the dynamic fracture of nominally brittle polymers
Davy Dalmas, Claudia Guerra, Julien Scheibert +1
Linear Elastic Fracture Mechanics (LEFM) provides a consistent framework to evaluate quantitatively the energy flux released to the tip of a growing crack. Still, the way in which…
Understanding fast macroscale fracture from microcrack post mortem patterns
Claudia Guerra, Julien Scheibert, Daniel Bonamy +1
Dynamic crack propagation drives catastrophic solid failures. In many amorphous brittle materials, sufficiently fast crack growth involves small-scale, high-frequency microcracking…
Origin and tailoring of the antiferromagnetic domain structure in -FeO thin films unraveled by statistical analysis of dichroic spectro-microscopy (X-PEEM) images
Odile Bezencenet, Daniel Bonamy, Rachid Belkhou +2
The magnetic microstructure and domain wall distribution of antiferromagnetic -FeO epitaxial layers is determined by statistical image analyses. Using dichroic spectro-m…
