Abstract

An Image correlation technique to evaluate the structural properties and behavior of the Friction Stir Welds (FSW) is presented. The technique used is Sub-Pixel Digital Image Correlation (SPDIC). Four weld samples made of Al-2219 and Al-2195 alloys but different surface treatments are tested under tensile loads and the digital images of these samples are correlated using SPDIC. Stress-strain graphs and strain contours are obtained from the results. From the stress-strain graphs the structural properties and the behavior of the weld material are determined. The results indicate that SPDIC is a steadfast tool to determine the structural behavior and material properties of the weld samples.
