Full field residual stress determination using hole-drilling and electronic speckle pattern interferometry (ESPI) with phase unwrapping method

Full field residual stress determination using hole-drilling and electronic speckle pattern interferometry (ESPI) with phase unwrapping method

The hole-drilling strain gauge technique has become a standard method in measuring residual stresses [1]. Moiré interferometry combining hole-drilling method opens additional opportunity for full-field residual stress measurement using optical interferometry [2]. The optical moiré method has a no...
