Contact of dissimilar elastic cylinders under normal and tangential loading

Abstract T he interfacial tractions induced by normal contact between dissimilar elastic cylinders are first re-evaluated, exploiting self-similarity and allowing for the influence of shear tractions on normal surface displacement. Subsequently, a tangential force less than that necessary to cause sliding is applied, and the modified traction distribution deduced. The effect of cycling the tangential force is also investigated, thus simulating the behaviour of the contact under fretting conditions. Results are compared with those predicted by the classical Mindlin-Cattaneo analysis for elastically similar bodies.
