Journal ArticleDOI
Evolution of real contact area under shear and the value of static friction of soft materials.
Riad Sahli,Gaël Pallares,Christophe Ducottet,I. Ben Ali,S. Al Akhrass,Matthieu Guibert,Julien Scheibert +6 more
TL;DR: The origin of static friction is investigated, the threshold force at which a frictional interface starts to slide, and for rough contacts involving rubber or human skin, the real contact area significantly decreases under increasing shear, well before the onset of sliding.
Journal ArticleDOI
Continuum contact models for coupled adhesion and friction
TL;DR: In this paper, the authors develop two new contact models for coupled adhesion and friction, and discuss them in the context of existing models proposed in the literature, which are able to describe sli...
Journal ArticleDOI
Shear-Induced Anisotropy in Rough Elastomer Contact
Riad Sahli,Gaël Pallares,Antonio Papangelo,Antonio Papangelo,Michele Ciavarella,Michele Ciavarella,Christophe Ducottet,Nicolas Ponthus,Julien Scheibert +8 more
TL;DR: It is shown that smooth sphere-plane contacts have the same shear-induced anisotropic behavior as individual microjunctions, with a common scaling law over 4 orders of magnitude in the initial area.
Journal ArticleDOI
Shear-induced contact area anisotropy explained by a fracture mechanics model.
Antonio Papangelo,Antonio Papangelo,Julien Scheibert,Riad Sahli,Gaël Pallares,Michele Ciavarella,Michele Ciavarella +6 more
TL;DR: In this article, a fracture mechanics model where two phenomenological mode-mixity functions are introduced to describe the weak coupling between modes I and II or I and III, which changes the effective toughness of the interface is presented.
Journal ArticleDOI
Continuum contact models for coupled adhesion and friction
TL;DR: Two new continuum contact models for coupled adhesion and friction are developed, able to describe sliding friction even under tensile normal forces, which seems reasonable for certain adhesion mechanisms.
