Both Surface Removal-Both Surface X-Ray Diffraction Method for Residual Stress Measurement in a Hollow Cylinder

Abstract

The authors proposed in this paper a new method of X-ray diffraction to measure three principal residual stresses in a hollow cylinder. With thin layers of equal thickness removed from both surfaces of a hollow cylinder, surface stresses are measured by X-ray on both surfaces, and then the residual stress distributions can be calculated from both surfaces at the same time. As an application of the new method, the authors measured the residual stresses of a heat treated hollow cylinder of STPT 38.
