Discrete dislocation analysis of size effects in thin films Academic Article uri icon

abstract

  • A discrete dislocation plasticity analysis of plastic deformation in metal thin films was investigated. A two-dimensional plane-strain formulation with only edge dislocations was used in the calculation. The analysis showed that a hard boundary layer forms at the interface between the film and the substrate, which does not scale with the film thickness giving rise to a size effect.
