Abstract: A theoretical model is developed to investigate the effects of the nanoscale twin and the dislocation pileup at the twin boundary on crack blunting in nanocrystalline materials. In the model, the nanoscale twin as a… read more here.

Abstract: Abstract The effects of the nanotwin and dislocation pileup at the twin boundary on lattice dislocation emission from a surface semi-elliptical blunt crack in deformed nanocrystalline materials (NCMs) are investigated. The nanotwin as a stress… read more here.
