Experimental analysis of the stick-slip characteristics of faults at different loading rates. [PDF]

open access: yesPLoS ONE, 2020
In deep underground engineering, in a large spatial, high-stress environment, rapid excavation is likely to affect the loading rate of the fault structure and to cause stick-slip.

Experimental and numerical study of stick–slip phenomenon in granular materials [PDF]

open access: yesScientific Reports
The stick–slip is a characteristic phenomenon of various mechanical systems, occurring when two bodies slide relative to each other. Friction plays a dominant role in this phenomenon, transitioning from static to dynamic when sudden movements take place.
