An intersonic slip pulse at a frictional interface between dissimilar materials. Adams, G. G. J. Appl.

The applied shear stress is less than that which is required to produce overall sliding of the two bodies. The possible existence of a slip pulse is investigated, i.e., a finite-width region, on the interface, of altered normal and shear stress which satisfies the Amontons-Coulomb law of friction.
