Resumo(s)
The incremental hole-drilling technique was applied to determine residual stress profiles
in shot-peened steel layers. The accuracy of using an enhanced Digital Speckle Pattern
Interferometry technique for measuring the strain relaxation arising around the drilled holes and,
consequently, the in-depth residual stress distribution induced by shot-peening, was evaluated. The
experimental results were systematically compared with those determined using standard electric
strain-gauges. The X-ray diffraction technique was chosen as reference due to its high accuracy to
determine shot-peening residual stresses.
