Theoretical and numerical investigations of single arm dislocation source controlled plastic flow in FCC micropillars
The 'dislocation source'controlled plastic behaviors in submicron single crystals, which differ
significantly from macroscopic plastic flow, are widely observed in recent in situ TEM tests. In …
