Abstract: A method is described for combining incremental hole drilling with holographic interferometry to determine the distribution of in-plane residual stresses as a function of depth below the surface. ...

Abstract: The strain gauge rosette hole drilling method is often used for determining residual stresses versus depth to depths on the order of 0.5–1.5 mm. Frequently, it is of interest to find stress ...

Abstract: A technique is described for the rapid determination of residual stresses through the combined use of hole drilling and holographic interferometry. A small diameter blind hole is drilled into ...
