Abstract
In this paper, the measurement of residual stress by the combination of Hole drilling, slitting and Digital Image Correlation methods and history of activities in this area have been investigated. To this end, the principles of the hole drilling, according to ASTM E837 and slitting methods have been discussed. Subsequently, the principles of digital image correlation and the methods used to calculate the correlation coefficient are investigated. To use the proposed method, related works done in recent years have been studied. For this purpose, related articles have been extracted and the main points for evaluation of residual stress using hole drilling and digital image correlation methods have been investigated. By reviewing past research done in the field of residual stress and examining the points made in the research, it has been determined that digital image correlation and central hole drilling methods can be used to measure the residual stresses in any industrial parts with high precision.
