Stick-slip is caused by the surfaces alternating between sticking to each other and
sliding over each other, with a corresponding change in the force of friction.
Typically, the static friction coefficient between two surfaces is larger than the
dynamic friction coefficient.
Recently, this motion is described more precisely than before by the use of the
bristle model, such as the LuGre model, as far as the rigid body on the rigid
surface is concerned.
In this case, the behavior change of the stick-slip motion is presented, when it
is applied to the elastic bodies.
When the spring property of the mass-spring system and shear stiffness of
the support plate have the same dynamic characteristics, then the stick-slip motion
continues without damping.
