Contact between rough surfaces: mechanical and transport phenomena at small scales (INVITED)

Abstract eng:
Normal contact between solids with rough self-affine surfaces is studied. Elastic and elastic-plastic solids are considered in the framework of classical and generalized continua. The following questions were investigated: evolution of the contact area and its morphology, fluid flow through the contact interface and the near-percolation behavior, energy transfer across the contact interface is also considered. Numerical results obtained using the finite and the boundary element methods are compared with analytical and semi-analytical models.
