Evolution of real contact area under shear and the value of static friction of soft materials
The frictional properties of a rough contact interface are controlled by its area of real contact,
the dynamical variations of which underlie our modern understanding of the ubiquitous rate …

Continuum contact models for coupled adhesion and friction
JC Mergel, R Sahli, J Scheibert… - The Journal of …, 2019 - Taylor & Francis
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 …

An asperity-based statistical model for the adhesive friction of elastic nominally flat rough contact interfaces
Contact mechanics-based models for the friction of nominally flat rough surfaces have not
been able to adequately capture certain key experimentally observed phenomena, such as …

Shear-induced anisotropy in rough elastomer contact
True contact between randomly rough solids consists of myriad individual microjunctions.
While their total area controls the adhesive friction force of the interface, other macroscopic …

Texture-induced modulations of friction force: the fingerprint effect
Modulations of the friction force in dry solid friction are usually attributed to macroscopic stick-
slip instabilities. Here we show that a distinct, quasistatic mechanism can also lead to nearly …

Do uniform tangential interfacial stresses enhance adhesion?
We present theoretical arguments, based on linear elasticity and thermodynamics, to show
that interfacial tangential stresses in sliding adhesive soft contacts may lead to a significant …

[HTML][HTML] Buckling and post-buckling of a stiff film resting on an elastic graded substrate
Systems consisting of a hard layer resting on an elastic graded soft substrate are frequently
encountered both in nature and industry. In this paper, we study the surface wrinkling …
