Dislocation breakaway from nanoparticle array linear complexions: Plasticity mechanisms and strength scaling laws
Divya Singh, Daniel S. Gianola, Timothy J. Rupert
Linear complexions are stable defect states, where the stress field associated with a dislocation induces a local phase transformation that remains restricted to nanoscale dimensio…

Solid Solution Strengthening and Softening Due to Collective Nanocrystalline Deformation Physics
Timothy J. Rupert
Solid solution effects on the strength of the finest nanocrystalline grain sizes are studied with molecular dynamics simulations of different Cu-based alloys. We find evidence of b…

Strain localization in a nanocrystalline metal: Atomic mechanisms and the effect of testing conditions
Timothy J. Rupert
Molecular dynamics simulations are used to investigate strain localization in a model nanocrystalline metal. The atomic mechanisms of such catastrophic failure are first studied fo…
