MECHANICAL STICK-SLIP VIBRATIONS
International Journal of Bifurcation and Chaos, 1995In this paper we consider the behavior of a two degree-of-freedom mechanical system incorporating static and dynamic friction, assumed to be a decreasing function of the relative sliding velocity. The model consists of two blocks linked by springs, which ride upon a moving belt.

An Example of Stick-Slip Waves
Comptes Rendus de l'Académie des Sciences - Series IIB - Mechanics, 2000Summary: An analytical solution representing a family of stick-slip waves is obtained in a simple example modelling the dynamic behaviour of an elastic cylindrical tube in contact with Coulomb's friction with a rigid rotating cylinder. This family of waves, representing the non-trivial periodic responses of a continuous system with one space variable ...

Abstract Simultaneous measurements of momentary friction and electrical resistance using the hoop apparatus have resulted in new insights into the behavior of the ubiquitous thin interfacial films at contact spots. The experimental focus of the present paper is the amplitude of the stick-slip motion of a multifiber slider as a function of the ...

Among the class of polymer extrusion instabilities, collectively known asmelt fracture (1), the stick-slip instability is the only one that is associated with pressure and extrudate flow rate oscillations, observedwhile the throughput is controlled.

Europhysics Letters (EPL), 2001
Sliding of adhesive boundary lubricated surfaces immersed in aqueous solutions has been studied. Under certain conditions inverted stick-slip motion is observed where, in contrast to conventional stick-slip, the friction spikes point down rather than up and the transition from smooth to stick-slip sliding occurs above rather than below some critical ...

Experimental study of stick‐slip behaviour
International Journal for Numerical and Analytical Methods in Geomechanics, 2004AbstractSimple axi‐symmetric uni‐axial compression tests have been realized on dry loose samples of glass beads (diameters d: d=0.2 ± 0.05 mm, 0.75 ± 0.1 mm, or 3 mm) and on Hostun sand under small lateral confinement, σ3<60 kPa, using different sample sizes.

Naive model for stick-slip processes
The European Physical Journal E, 2007This paper is a tutorial description of stick-slip in soft materials (rubber beads, gels) where inertial effects are negligible. A typical example is a rubber sphere, pressed against a glass surface (JKR contact). The sphere is driven from the top at a prescribed velocity U ( approximately 100 microm/s).
