Paper Abstract

The phase-shifting holographic interferometry combined with the blind-hole method for measuring residual stresses was introduced in this paper. The relationship between the out-of- plane displacements and the residual stresses relieved from blind-hole drilling was examined. Combining this relationship and the theory of holographic interferometry, it is found that full- field out-of-plane displacements can be measured by taking one interference fringe pattern even when the illumination and viewing directions are arbitrary. By using this measured displacement field, it is sufficient to determine the residual stresses with three relative out-of- plane displacements measured along the radial directions. Adopting this newly developed technique to measure a known residual stress in an aluminum specimen, good agreement between the experimental data and the known values were found to agree well with respect to eachother.
