Sound and light from fractures in scintillators
A. Tantot, S. Santucci, O. Ramos +7
Prompted by intriguing events observed in certain particle-physics searches for rare events, we study light and acoustic emission simultaneously in some inorganic scintillators sub…
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…
Attractive and repulsive cracks in a heterogeneous material
Pierre-Philippe Cortet, Guillaume Huillard, Loïc Vanel +1
We study experimentally the paths of an assembly of cracks growing in interaction in a heterogeneous two-dimensional elastic brittle material submitted to uniaxial stress. For a gi…
Statistical properties of microcracking in polyurethane foams under tensile test, influence of temperature and density
Stéphanie Deschanel, Loïc Vanel, Gérard Vigier +2
We report tensile failure experiments on polyurethane (PU) foams. Experiments have been performed by imposing a constant strain rate. We work on heterogeneous materials for whom th…
Slow crack growth in polycarbonate films
Pierre-Philippe Cortet, Stéphane Santucci, Loic Vanel +1
We study experimentally the slow growth of a single crack in polycarbonate films submitted to uniaxial and constant imposed stress. The specificity of fracture in polycarbonate fil…
Imaging the stick-slip peeling of an adhesive tape under a constant load
Pierre-Philippe Cortet, Matteo Ciccotti, Loic Vanel
Using a high speed camera, we study the peeling dynamics of an adhesive tape under a constant load with a special focus on the so-called stick-slip regime of the peeling. It is the…
Subcritical crack growth in fibrous materials
Stéphane Santucci, Pierre-Philippe Cortet, Stéphanie Deschanel +2
We present experiments on the slow growth of a single crack in a fax paper sheet submitted to a constant force . We find that statistically averaged crack growth curves can be d…
Slow crack growth : models and experiments
Stéphane Santucci, Loic Vanel, Sergio Ciliberto
The properties of slow crack growth in brittle materials are analyzed both theoretically and experimentally. We propose a model based on a thermally activated rupture process. Cons…
Gaussian Statistics of Fracture Surfaces
Stéphane Santucci, Joachim Mathiesen, Knut Jørgen Måløy +6
We analyse the statistical distribution function for the height fluctuations of brittle fracture surfaces using extensive experimental data sampled on widely different materials an…
Super-Arrhenius dynamics for sub-critical crack growth in disordered brittle media
P. -P. Cortet, L. Vanel, S. Ciliberto
Taking into account stress fluctuations due to thermal noise, we study thermally activated irreversible crack growth in disordered media. The influence of material disorder on sub-…
Fracture Surfaces as Multiscaling Graphs
Eran Bouchbinder, Itamar Procaccia, Stephane Santucci +1
Fracture paths in quasi-two-dimenisonal (2D) media (e.g thin layers of materials, paper) are analyzed as self-affine graphs of height as a function of length . We sho…
Footprints in Sand: The Response of a Granular Material to Local Perturbations
Junfei Geng, D. Howell, E. Longhi +5
We experimentally determine ensemble-averaged responses of granular packings to point forces, and we compare these results to recent models for force propagation in a granular mate…
