Stick-slip-separation waves in a rotating shaft-bush system

Stick-slip waves between elastic and rigid half-spaces

This paper is devoted to the construction of analytic solution of stick-slip waves crossing the interface between an elastic half-space and a rigid one under unilateral contact and Coulomb friction. The method of solution is based on the analytic continuation method of Radok's complex potentials within the framework of steady elastodynamical problems. The governing equations combined with the b...

Stabilizing stick-slip friction.

Even the most regular stick-slip frictional sliding is always stochastic, with irregularity in both the intervals between slip events and the sizes of the associated stress drops. Applying small-amplitude oscillations to the shear force, we show, experimentally and theoretically, that the stick-slip periods synchronize. We further show that this phase locking is related to the inhibition of slo...

Flatness and stick-slip stabilization

The origin of this report lies in the very interesting discussions with Chal-lamel of the CGES at Ecole des Mines de Paris and with Hugues Mounier of Ecole des Mines de Nantes.

Subsurface Cracks Under Conditions of Slip, Stick, and Separation Caused by a Moving Compressive Load

The Mode I and II stress intensity factors (K„ Kn) at the two tips of a subsurface crack subjected to a moving compressive load are studied. Coulomb friction along the crack faces results in a number of history dependent slip-stick configurations and nonsymmetric variation in K7 and K/7. The formulation used to study this variation involves a singular integral equation in two variables which mu...
