Abstract
Computer simulations are presented where a model for a two-dimensional colloidal crystal confined to corrugated walls is exposed to a steady-state shear deformation. Following up on an earlier study, where average velocity profiles of the particles in the crystal across the slit have been obtained, we now analyse the time dependence of the particle motions and of the resulting shear forces. We discuss the extent to which the resulting irregular and damped oscillatory motions can be associated with stick-slip motions familiar from friction phenomena.
