Hill Engineering recently posted a new case study detailing our research into an extension of the contour method we call PSR biaxial mapping. This new technique generates two-dimensional maps of additional residual stress components over the same plane as the original contour method measurement.
The case study goes on to detail what the PSR biaxial mapping method entails, as well as example results from a residual stress measurement performed on a nickel alloy forging. The resulting plots show hoop residual stress measured from the contour method and radial residual stress measured from PSR biaxial mapping.
PSR biaxial mapping has been used to measure 2D residual stress maps for a variety of applications including: a quenched aluminum extrusion, a stainless steel welded plate, a complex nuclear power plant nozzle mockup containing a dissimilar metal weld, an aluminum T-section, a stainless steel plate with a dissimilar metal weld, a titanium plate with an electron beam weld, and a nickel alloy forging.
Please, give the case study a read and do not hesitate to contact us with any further questions about PSR biaxial mapping or any of the other
