Interest of geophysical methods to determine the evolution and the spatial distribution of sedimentary deposits upstream of run-of-the-river dams (Upper Rh{ô}ne, France)
Anne Weit, Thierry Winiarski, Brice Mourier +2
Hydraulic structures such as dams have a direct or indirect influence on the hydro-sedimentary functioning of rivers. They can impact the sediment continuity of the river and can c…
Adhesion in soft contacts is minimum beyond a critical shear displacement
C. Oliver, D. Dalmas, J. Scheibert
The most direct measurement of adhesion is the pull-off force, i.e. the tensile force necessary to separate two solids in contact. For a given interface, it depends on various expe…
Linking the dust and chemical evolution: Taurus and Perseus -- New collisional rates for HCN, HNC, and their C, N, and H isotopologues
D. Navarro-Almaida, C. T. Bop, F. Lique +18
HCN, HNC, and their isotopologues are ubiquitous molecules that can serve as chemical thermometers and evolutionary tracers to characterize star-forming regions. Despite their impo…
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…
Parking search in the physical world: Calculating the search time by leveraging physical and graph theoretical methods
Nilankur Dutta, Thibault Charlottin, Alexandre Nicolas
Parking plays a central role in transport policies and has wide-ranging consequences: While the average time spent searching for parking exceeds dozens of hours per driver every ye…
A versatile flexure-based 6-axes force/torque sensor and its application to tribology
M Guibert, C Oliver, T Durand +5
Six-axes force/torque sensors are increasingly needed in mechanical engineering. Here, we introduce a flexure-based design for such sensors, which solves some of the drawbacks of t…
Model-based assessment of the risks of viral transmission in non-confined crowds
Willy Garcia, Simon Mendez, Baptiste Fray +1
This work aims to assess the risks of Covid-19 disease spread in diverse daily-life situations (referred to as scenarios) involving crowds of maskless pedestrians, mostly outdoors.…
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,…
Contact with coupled adhesion and friction: Computational framework, applications, and new insights
Janine C. Mergel, Julien Scheibert, Roger A. Sauer
Contact involving soft materials often combines dry adhesion, sliding friction, and large deformations. At the local level, these three aspects are rarely captured simultaneously,…
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…
A minimal model for slow, sub-Rayleigh, super-shear and unsteady rupture propagation along homogeneously loaded frictional interfaces
Kjetil Thøgersen, Henrik Andersen Sveinsson, David Skålid Amundsen +3
In nature and experiments, a large variety of rupture speeds and front modes along frictional interfaces are observed. Here, we introduce a minimal model for the rupture of homogen…
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…
How reproducible are methods to measure the dynamic viscoelastic properties of poroelastic media?
Paolo Bonfiglio, Francesco Pompoli, Kirill V. Horoshenkov +30
There is a considerable number of research publications on the acoustical properties of porous media with an elastic frame. A simple search through the Web of ScienceTM (last acces…
Continuum contact models for coupled adhesion and friction
Janine C. Mergel, Riad Sahli, Julien Scheibert +1
We develop two new continuum contact models for coupled adhesion and friction, and discuss them in the context of existing models proposed in the literature. Our new models are abl…
Inelastic deformation during sill and laccolith emplacement: Insights from an analytic elastoplastic model
J. Scheibert, O. Galland, A. Hafver
Numerous geological observations evidence that inelastic deformation occurs during sills and laccoliths emplacement. However, most models of sill and laccolith emplacement neglect…
The Lagrangian coordinate system and what it means for two-dimensional crowd flow models
Femke van Wageningen-Kessels, Ludovic Leclercq, Winnie Daamen +1
A continuum crowd flow model is reformulated in the Lagrangian coordinate system. The system has proven to give computational advantages over the traditional Eulerian coordinate sy…
The small binary asteroid (939) Isberga
B. Carry, A. Matter, P. Scheirich +29
In understanding the composition and internal structure of asteroids, their density is perhaps the most diagnostic quantity. We aim here to characterize the surface composition, mu…
