Abstract
Current research on nanocrystalline metals and nanoscale multilayer thin films suggests
extraordinary plastic strength is due to confinement of slip to individual grains or layers. To
assess the magnitude of confinement, a Peierls model of slip transmission of a screw dislocation
across a coherent, non-slipping interface is presented. The results reflect that large interfacial
