Abstract In this paper, a technique that combines digital image correlation and wire electrical discharge machining for the measurement of the residual strain is presented. The significant potential benefits of this work include noncontact, high-speed, and online measurement. A ring-core-based groove in the surface of the specimen is cut to release the residual stresses present inside the core. The deformation due to these stresses can be measured by digital image correlation to measure the relieved strains. Moreover, the sizes of the reference areas on the specimens and the tracks of these areas after wire electrical discharge machining are investigated. The proposed method is applied to six different specimens to characterize their relieved strains. View Full-Text
