Dynamics of Slip Fronts at Frictional Interfaces: Analysis of Slip Precursors and Rupture Velocity

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer, Vladislav Yastrebov

The rupture dynamics of earthquakes span a considerable range, from slow to super-shear ruptures. Rupture speed has a major influence on the generation of strong ground motions, yet our understanding of the mechanisms causing these variations in the ruptur ...

Dynamics of Slip Fronts at Frictional Interfaces: Analysis of Slip Precursors

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer

The transition from sticking to sliding of frictional interfaces is a phenomenon of importance for many physical systems in nature as well as in engineering. This transition is marked by the occurrence of local slip events, often called precursors, which a ...

Third body effects on friction and wear during the fretting of steel contacts

Stefano Mischler

Frettingwear proceeds through particle detachment from the contacting surfaces which, while trapped in the contact zone, can affect the frictional and wear response. Ball-on-flat fretting experiments were carried out between steel specimens under gross sli ...

New slip synthesis and theoretical approach of CVT slip control

Yves Rothenbühler

Today's vehicle must be efficient in terms of gas (CO2, NOx) emissions and fuel consumption. Due to improvements in material and oil, the continuous variable transmission (CVT) is now making a breakthrough in the automotive market. The CVT decouples the en ...

Molecular Dynamics Simulations of Interfacial Sliding in Carbon-Nanotube/Diamond Nanocomposites

William Curtin

Molecular dynamics simulations are reported for the pullout force and interfacial friction of single-and multiwall carbon nanotubes (CNT) with interwall sp(3) bonds embedded in a diamond matrix. The van der Waals interaction and sp(3) bonding are shown to ...

Influence of emulsion composition on lubrication capacity and texture perception

Stefano Mischler

P>The role of fat content and type of surfactant for oral friction processes and texture perception of oil-in-water emulsions was assessed. Emulsions at 22% and 33% fat content containing either sodium caseinate or a sucrose ester as emulsifier were compar ...

Nouveaux concepts de locomotion pour véhicules tout-terrain robotisés

Michel Lauria

Robotic ground vehicles are mechanisms that use gravity and contact forces with the ground to perform motion. They can either be wheeled, tracked or legged. In this thesis we will focus on n-wheeled vehicles able to perform ground following motion with all ...

Multiscale modeling of failure in metal matrix composites

William Curtin

A multiscale approach to composite failure, in which detailed information on small-scale micromechanics is incorporated approximately yet accurately into larger-scale models capable of simulating extensive damage evolution and ultimate failure, is applied ...

Finite-element modeling of dry sliding wear in metals

Jean-François Molinari, Raul Radovitzky

This paper is concerned with the calibration and validation of a finite-element model of dry sliding wear in metals. The model is formulated within a Lagrangian framework capable of accounting for large plastic deformations and history-dependent material b ...
