This research presents a systematic study of the interfacial behaviour of tyred systems. A simplified two-dimensional contact model of an elastic strip, shrink-fitted onto a wheel, and subjected to different rolling contact conditions, has been developed. This model enables us to characterise the behaviour at the strip/substrate interface caused by a quasi-static application of moving loads on the surface of the layer. The solution is compared to the stationary load case and regimes of local slip, full stick, separation and frictional creep are identified and mapped for a variety of loading conditions, materials and geometries.
