Finite size effects on crack front pinning at heterogeneous planar interfaces: Experimental, finite elements and perturbation approaches
Sylvain Patinet, L Alzate, E Barthel +3
Understanding the role played by the microstructure of materials on their macroscopic failure properties is an important challenge in solid mechanics. Indeed, when a crack propagat…
Crack Front Segmentation and Facet Coarsening in Mixed-Mode Fracture
Chih-Hung Chen, Tristan Cambonie, Veronique Lazarus +3
A planar crack generically segments into an array of "daughter cracks" shaped as tilted facets when loaded with both a tensile stress normal to the crack plane (mode I) and a shear…
Increased magnetic damping of a single domain wall and adjacent magnetic domains detected by spin torque diode in a nanostripe
Steven Lequeux, Joao Sampaio, Paolo Bortolotti +11
We use spin-torque resonance to probe simultaneously and separately the dynamics of a magnetic domain wall and of magnetic domains in a nanostripe magnetic tunnel junction. Thanks…
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…
Intermittent stick-slip dynamics during the peeling of an adhesive tape from a roller
Pierre-Philippe Cortet, Marie-Julie Dalbe, Claudia Guerra +4
We study experimentally the fracture dynamics during the peeling at a constant velocity of a roller adhesive tape mounted on a freely rotating pulley. Thanks to a high speed camera…
Vers une mesure non destructive de la qualité des bois de lutherie
Marc Louis Maurice François
An ultrasonic measurement of the stiffness tensor of a spruce specimen is made for different moisture content. We show that a known scalar indicator describres correctly the qualit…
