Journal of Applied Physics 111, no. 10 (2012): 103522. DOI: 10.1063/1.47184320021-89791089-7550https://nrs.harvard.edu/URN-3:HUL.INSTREPOS:37373454In this paper, dislocation climb is incorporated in a two-dimensional discrete dislocation dynamics model. Calculations are carried out for polycrystalline thin films, passivated on one or both surfaces. Climb allows dislocations to escape from dislocation pile-ups and reduces the strain- hardening rate, especially for fully passivated films. Within the framework of this model, climb modifies the dislocation structures that develop during plastic deformation and results in the formation of pile-ups on slip planes that do not contain any dislocation sources.en-USGeneral Physics and AstronomyJournal Article2022-10-3110.1063/1.4718432
