X-ray Measurement of Residual Stresses in a Plate with Both Surface Diffractions under Single Surface Removal or Both Surface Removal

Abstract

The former X-ray methods of residual stress distribution measurement in a plate is to measure the surface stress by X-ray on one surface, removed surface or nonremoved one, after successive thin layer removal from one surface. The authors propose in this paper new methods to obtain the residual stress distribution in a plate from the surface stresses measured by X-ray on both surfaces during the single surface removal or the both surface removal and show an example of the new methods applied to a quenched and tempered alloy steel plate of SKS 5.
