Functional properties of rough surfaces from an analytical theory of mechanical contact

Abstract The basic ideas behind a contact mechanics theory for randomly rough surfaces are presented. is based on studying the interface at increasing magnification. At lowest magnification, no surface roughness can be detected and nature of between two solids in this limit determined using standard numerical methods (e.g., FEM). predicts how influences (or modifies) stress distribution interfacial gap. flexible applied to elastic, viscoelastic, elastoplastic solids, as well layered materials. Applications leakage seals, stiffness, electric thermal resistance, rubber friction, adhesion, mixed lubrication Graphical abstract
