Abstract

Aiming to understand the fracture mechanism accompanying the small fatigue crack propagation in polycrystalline metallic materials like steels the full-field strain measurement using digital image correlation (DIC) method was performed. The developed experimental approach was applied to study the small fatigue crack behavior in body-centered Fe-Cr ferritic stainless steel with the relatively large grain size of about 350 µm. The high spatial measurement accuracy of the strain field analysis was performed using the unique patterning technique with a characteristic speckle size of approximately 10 µm.
