WebThe characteristic profile of the frictional force during the unstable motion is depicted in Fig. 2 [ 1-5 ]. This is the stick-slip motion: the probe is held at certain sites, the frictional force starts to raise until the probe separation occurs and the frictional force jumps to a certain minimum. Fig. 2. WebJul 29, 2011 · The stick-slip phenomenon is simply described as a simple contact model which is a rigid body contacted on a sloped surface. If the calculated friction coefficient between the body and sloped surface is less than the static friction coefficient, the body should be stuck.
