摘要: Abstract Molecular dynamics simulation was performed to investigate influence of (0 1 0) twist boundary on intercrystalline crack propagation nano-nickel bicrystal films. The plasticity films decreases with increasing angle. Crack arrest in the film angle 0° is attributed occurrence plastic deformation whole and hence stress concentration at tip released. However, new initiation higher around grain boundary, where dislocation motion impeded thus severe induced.
