Collective Asperity Dynamics and the Origin of Static Friction
arXiv:2510.14769v2 Announce Type: replace-cross Abstract: Solid interfaces resist sliding up to a threshold shear force, called static friction, beyond which they start moving and their resistance drops to the kinetic friction. Static friction at rough interfaces has long been described empirically using system-specific coefficients tabulated in engineering handbooks. Here, through nanometer-resolution sliding experiments, we show that it is set by a friction overshoot during the onset of...
