WebThe stick-slip phenomenon is often associated with the friction between two contacting bodies. Some analytical models to describe the stick-slip phenomena were proposed. Numerically, Nakano et al. [5-8] studied the stick-slip contact of a sliding system between a soft indenter and a rigid moving floor for preventing stick to occur. Webrocks stick together along the fault line, held together by static friction, until they suddenly slip, resulting in an earthquake. This stick and slip behavior is complex and modeling requires more sophisticated methods than the well-known static and dynamic friction theories { par-ticularly, the rate- and state- dependent friction model.

WebThe rate and state dependent friction law based on laboratory experimental results has been widely accepted to describe the friction and sliding behavior of rock.
