An asperity-based statistical model for the adhesive friction of elastic nominally flat rough contact interfaces
Yang Xu, Julien Scheibert, Nikolaj Gadegaard +1
Contact mechanics-based models for the friction of nominally flat rough surfaces have not been able to adequately capture certain key experimentally observed phenomenona, such as t…
Finite deformations govern the anisotropic shear-induced area reduction of soft elastic contacts
J. Lengiewicz, M. de Souza, M. Lahmar +4
Solid contacts involving soft materials are important in mechanical engineering or biomechanics. Experimentally, such contacts have been shown to shrink significantly under shear,…
Onset of sliding of elastomer multicontacts: failure of a model of independent asperities to match experiments
Julien Scheibert, Riad Sahli, Michel Peyrard
Modelling of rough frictional interfaces is often based on asperity models, in which the individual behaviour of individual microjunctions is assumed. In the absence of local measu…
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…
Propagation Length of Self-healing Slip Pulses at the Onset of Sliding: A Toy Model
Oleg Braun, J Scheibert
Macroscopic sliding between two solids is triggered by the propagation of a micro-slip front along the frictional interface. In certain conditions, sliding is preceded by the propa…
Slow slip and the transition from fast to slow fronts in the rupture of frictional interfaces
Jørgen Kjoshagen Trømborg, Henrik Andersen Sveinsson, Julien Scheibert +3
The failure of the population of micro-junctions forming the frictional interface between two solids is central to fields ranging from biomechanics to seismology. This failure is m…
Stress Field at a Sliding Frictional Contact: Experiments and Calculations
Julien Scheibert, Alexis Prevost, Georges Debrégeas +2
A MEMS-based sensing device is used to measure the normal and tangential stress fields at the base of a rough elastomer film in contact with a smooth glass cylinder in steady slidi…
Probing the micromechanics of a multi-contact interface at the onset of frictional sliding
Alexis Prevost, Julien Scheibert, Georges Debrégeas
Digital Image Correlation is used to study the micromechanics of a multi-contact interface formed between a rough elastomer and a smooth glass surface. The in-plane elastomer defor…
Local contact stress measurements at a rough interface
J. Scheibert, A. Prevost, J. Frelat +2
An original MEMS-based force sensing device is designed which allows to measure spatially resolved normal and tangential stress fields at the base of an elastomeric film. This devi…
