The Molecular Dynamic considers the matter with molecular details. The Molecular Dynamic simulation is relevant for try to estimate the threshold size of the roughness on the friction coefficient, and for obtain some physical information on the rheology of the interfacial process zone. For the experiments, the topographic functionnalization of the spherical tips has been made by chemical and physical processes to obtain various roughnesses (few nm to 20/30 nm). Friction tests on PC have shown that the interfacial shear stress versus the mean contact pressure depends on the roughness.
