Abstract
AbstractA synchronized analysis of strain localization and slip system interaction, with full‐field strain mapping, in the vicinity of a notch tip in aluminum single crystal is presented. Progressive strain accumulation, prominently along one of the slip shear bands, was demonstrated quantitatively under cyclic loading, using digital image correlation. This dominant slip band potentially critical for the nucleation and growth of a crack. Also, triple slip active regions found on the surface indicate the participation of all three in‐plane slip systems. Therefore, the use of either diagonal or weakly coupled hardening rule is recommended even in aluminum single crystals, instead of the commonly used isotropic models. Finally, the results from this work provide quantitative data on the progressive strain accumulation and localization around a notch under cyclic loading that can be used in model validation for single and polycrystal plasticity.
