N2 - A model based on a self consistent scheme is developed to account for the plastic behavior of f.c.c. nanocrystalline materials. The material is assimilated as a composite with two phases: the inclusion phase which represents the grain cores, and the matrix phase which represents both grain boundaries and triple junctions. Both phases exhibit an elastoplatic behavior. In the case of the inclusion phase, the glide of dislocations pilots the plastic deformation, while Coble creep and the mechanism of grain boundary sliding are responsible for the elastoplastic behavior of the matrix phase.
