Plasticity effects in incremental slitting measurement of residual stresses (2010, background): “Such a distribution but with even higher stress magnitudes can be found for the transverse stresses in a butt welded plate [34] or girth welded pipe [35].”
Measuring Multiple Residual-Stress Components using the Contour Method and Multiple Cuts (2010, methodology): “The deep hole method can measure multiple stress components through the thickness of a part but only provides a 1D stress profile [ 18 ].”
Laser surface-contouring and spline data-smoothing for residual stress measurement (2004, methodology): “Other relaxation methods, at least those that are commonly used, determine at most a 1-D depth profile,(3) although some can measure multiple stress components.(4) In all applications of the contour method to date, the surface contours were measured using a touch probe on a commercial Coordinate Mea”
