The present study focuses on application of Digital Image Correlation technique (DIC) to low cycle fatigue testing for localized strain measurement and capturing crack initiation event at relatively lower value of strain amplitude. Low cycle fatigue tests have been conducted on unnotched as well as notched tube specimen under different cyclic loading conditions. The validation exercise of the DIC systems has been carried out by conducting tests on unnotched tube specimens subjected to completely reversible loading under extensometer-controlled condition. This is followed by conducting strain-controlled test on notched tube specimen with a single sided through thickness transverse hole in the gauge region of the tube and subjected to remote cyclic axial and torsional loading conditions. During the test, measurement of the localized strain field information as well as capturing the crack initiation event at/ahead of notch have also been carried out on the outer surface of the tube specimen. Further, the applicability of the DIC measurement technique for curved geometry under such low strain amplitude and complex loading scenario has been evaluated by comparing the DIC measurements with their corresponding strain gauge measurements. DIC measurements are in good agreement with the strain gauge results.
