A Sideways Crack-Path Instability Amplified by Slow Loading
G. Pallares, O. Ramos, L. Vanel
Crack-path instabilities in solids are typically associated with high propagation velocities. In contrast, we show that nanoparticle-filled elastomers exhibit a sideways crack-path…
Shear-induced contact area anisotropy explained by a fracture mechanics model
A. Papangelo, J. Scheibert, R. Sahli +2
This paper gives a theoretical analysis for the fundamental problem of anisotropy induced by shear forces onan adhesive contact, discussing the experimental data of the companion L…
Shear-Induced Anisotropy in Rough Elastomer Contact
R. Sahli, G. Pallares, A. Papangelo +4
True contact between randomly rough solids consists of myriad individual micro-junctions. While their total area controls the adhesive friction force of the interface, other macros…
Roughness of oxide glass subcritical fracture surfaces
Gael Pallares, Frederic Lechenault, Matthieu George +4
An original setup combining a very stable loading stage, an atomic force microscope and an environmental chamber, allows to obtain very stable sub-critical fracture propagation in…
Anomalies in bulk supercooled water at negative pressure
Gaël Pallares, Mouna El Mekki Azouzi, Miguel Angel Gonzalez +4
Water is the most familiar liquid, and arguably the most complex. Anomalies of supercooled water have been measured during decades, and competing interpretations proposed. Yet, a d…
Fractoluminescence characterization of the energy dissipated during fast fracture of glass
Gael Pallares, Cindy L. Rountree, Ludovic Douillard +2
Fractoluminescence experiments are performed on two kinds of silicate glasses. All the light spectra collected during dynamic fracture reveal a black body radiator behaviour, which…
Effects of finite probe size on self-affine roughness measurements
F. Lechenault, G. Pallares, M. George +3
The roughness of fracture surfaces has been shown to exhibit self-affne scale invariance for a wide variety of materials and loading conditions. The range of scales over which this…
Crack opening profile in DCDC specimen
Gael Pallares, Laurent Ponson, Antoine Grimaldi +3
The opening profile of the cracks produced in the Double Cleavage Drilled Compression (DCDC) specimens for brittle materials is investigated. The study is achieved by combining Fin…
