Abstract

The application of digital image correlation (DIC) to analyze the heterogeneity deformation of single crystal aluminum during a micro-tensile test was demonstrated. Before testing the single crystal aluminum, a test was carried out on a steel material to evaluate the sensitivity of DIC during a tensile test experiment. The results obtained through DIC and strain gauge were compared. The Young's moduli of steel for loading and unloading, as determined by the DIC method, were found to be 201.6 and 200.5 GPa, respectively. The deformation heterogeneity in terms of the strain εx map obtained through the DIC method was characterized by a broadened band that was inclined at an angle of 75°.
