The goal of this work is the development of other experimental techniques to measure residual stresses, as alternative to the hole-drilling method with strain gages. The proposed experimental techniques are based on the use of Moiré Interferometry and in-plane Electronic Speckle Pattern Interferometry (ESPI). Both are field techniques allowing the assessment of in-plane displacements without contact and high resolution. Grating replication techniques were developed to record high quality diffraction gratings onto the specimen's surfaces. An optical set-up of laser interferometry was developed to generate the master grating (virtual). An in-plane ESPI set-up was also designed and implemented to measure displacements in one direction. The stress relaxation was promoted by the blind hole-drilling and the obtained fringe patterns (Moiré and speckle) were video recorded. Image processing techniques were applied to assess the in-plane strain field. A finite elements code (ANSYS®) was used to simulate the stresses relaxation process whose values were compared with the experimental data and to calculate the hole-drilling calibration constants.

“…In both cases, the residual stress field was computed establishing an appropriate stressdisplacement relationship by a Finite Element Method (FEM) code. According to Nelson [8] the displacements due to residual stresses relaxation are related between themselves through the following equations,…”

“…Let us now consider a typical error estimation, which follows from Inequality (21) and Relation (24), for the hole related to points 2-1 and 2 * -1 of Specimen ]1E (see Table 1). To do this we need an estimation of the error inherent in a determination of hole diameter increments Du and Dv.…”

“…The first approach independently developed by different authors includes various versions of the holographic interferometry method as a measurement tool [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Implementing holographic interferometric techniques for a measurement of the required deformation parameters gives the maximum possible sensitivity of the hole-drilling method with respect to residual stresses determination.…”

“…Residual stress has been assessed using a number of methods: hole drilling, the curvature method, X-ray diffraction, Raman spectrophotometer and neutron diffraction, and magnetic Barkhausen noise (MBN) [1][2][3][4][5][6]. Residual stress has been reported to be related to mechanical properties such as fatigue life, distortion, dimensional stability, and brittle fracture.…”
