Abstract

Residual stresses occur in many manufactured structures and components. Over the years, different techniques have been developed to measure residual stresses; nowadays the com-bination of Hole Drilling method (HD) with optical techniques is encountering increasing interest. The use of a high sensitivity optical technique instead of the strain gage rosette has the advantage to provide full field information without any contact with the sample by con-sequently reducing the cost and the time required for the measurement. During the years dif-ferent optical techniques have been applied such as moiré interferometry, digital holography and electronic speckle pattern interferometry (ESPI). In the present paper a short summary of the different adopted approaches is provided.
