Experimental investigation of early strain localizations on polycrystalline α-Fe in cyclic loading.

Résumé

A novel experimental approach has been devised to investigate the phenomenon of strain localization in polycrystalline α-Fe samples subjected to cyclic loading. During Low Cycle Fatigue (LCF) loading, local strain measurements were obtained along the width of the semi-circular notch in the specimen using an in-situ optical-based Digital Image Correlation (DIC) technique with a suitable resolution. The resultant strain fields were mapped onto the microstructure to identify the locations of plasticity and potential crack initiation sites.
