Abstract
The embedded-atom method is used to calculate the surface stresses and the interface stresses for several fcc metals and interfaces between them. While the surface stresses are all positive (i.e., they tend to put the underlying crystal in compression), in several instances (e.g., in the Pt/Ni system) negative interface stresses are found. The effects of the interface stresses on the elastic moduli of metallic multilayers are discussed.Keywords
