Stick-slip friction
===================

Understanding how slip at a frictional interface initiates is important for e.g. earthquake prediction and precision engineering.
The force needed to start sliding a solid object over a flat surface is classically described by a "static friction coefficient": a constant established by measurements.
It was recently questioned if such constant exists, as it was shown to be poorly reproducible.
Over the recent years I have proposed a novel theory for the onset of slip (formerly known as the "static friction coefficient") that is based on:

*   An armouring mechanism that results in few "soft spots" after slip :footcite:`ElSergany2023`.
*   A competition between disorder and elasticity that results in spatial correlations in stress :footcite:`deGeus2022`.
*   A phase-transition-like behaviour that results in a critical stress for slip (the "dynamic friction coefficient") :footcite:`deGeus2019`.
