Abstract

The paper is using the nonlocal field equations for modelling a nanocontact made from the thin films. The theory describes long-range interactions among the particles. An elastic layer loaded by a rigid indenter is considered. We show that the stress field is finite for all points and have a maximum value that does not occur at the boundary of the contact domain.
