Single 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 using X-ray diffraction to measure the distributions of three principal residual stresses in a hollow cylinder. The procedure involves the uniform removal of successive thin layers from an inner or outer surface of a hollow cylinder and surface stress measurements by X-ray on the inner and outer surfaces of it. Residual stress distributions are calculated from both surface stresses. The new method has a special feature of simple formulas. The authors give an example of measurement by applying the new method to a heat treated hollow cylinder (STPT 38).
