Static friction might be an illusion made by the rotation of kinetic friction. See: Nakano & Popov, Phys. Rev. E 102, 063001 (2020). journals.aps.org/pre/abstract/1…

Or static friction may actually be an illusion created by simple mechanical responses to solid viscoelasticity. See: Watanabe & Nakano, Phys. Rev. E 111, 065504 (2025). doi.org/10.1103/dn4g-c…

This simple toy model exhibits four types of dynamics, including stick-slip instability, without using artificial friction laws. The key is the lift-up motion of the rigid probe that slides against the viscoelastic solid. See: Watanabe & Nakano, Phys. Rev. E 111, 065504 (2025).
