Rate-State-Friction depends on the state of the system in operation.
Question for today: Rate-State-Friction is commonly observed as Stick-Slip behavior.
When the contact situation evolves with time, the friction depends on the system. I.e.,An indication of such is an initial decrease in friction transitioning into a situation in which friction increases with velocity.
For high sliding speeds and low loads the junction has less time to evolve - while at higher loads and relatively slower sliding speeds the contact situation has more time to evolve, resulting in stick-slip behavior.
Stick-Slip can occur in clutch type Limited slip differentials when the dynamic friction modification has not been set properly, for example, by using an LSD additive in a non-LS gear formulation. The sound or feeling is that of differential "chattering."
Stick-Slip behavior also results deep within the Earth as earthquakes.
