We numerically study a simple sliding system: a rigid mass pulled by a spring having strong in-plane stiffness anisotropy and a small misalignment angle. Simulations show that the apparent “stick” phase in this system is in reality a phase of very slow creep, followed by rapid sliding, slip. Surprisingly, the absolute value of the friction force remains almost constant from the very beginning of the “stick” phase, merely rotating in the sliding plane. We call this specific mechanism of apparent…
