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…
Surface deformations and wave generation by wind blowing over a viscous liquid
Anna Paquier, Frederic Moisy, Marc Rabaud
We investigate experimentally the early stage of the generation of waves by a turbulent wind at the surface of a viscous liquid. The spatio-temporal structure of the surface deform…
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…
Multiscale Stick-Slip Dynamics of Adhesive Tape Peeling
Marie-Julie Dalbe, Pierre-Philippe Cortet, Matteo Ciccotti +2
Using a high-speed camera, we follow the propagation of the detachment front during the peeling of an adhesive tape from a flat surface. In a given range of peeling velocity, this…
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…
Local rheological measurements in the granular flow around an intruder
A. Seguin, C. Coulais, F. Martinez +2
The rheological properties of granular matter within a two-dimensional flow around a moving disk is investigated experimentally. Using a combination of photoelastic and standard te…
