A finite element model of grain boundary sliding for nanostructured metals

Abstract:

Efforts to characterize and understand the mechanical behavior of nanocrystals have unveiled some unique features of deformation that are not commonly observed in polycrystals. In this work, we propose a continuum model describing the competing deformation mechanisms believed to determine the effective response of nanocrystalline materials. The model is based on explicitly accounting for grain-boundary deformation including sliding and other accomodation mechanisms, as well as for the interac...
