Abstract
A residual stress measurement method of a curved surface block includes steps of: locating a point at which a to-be-detected curved surface of a curved surface block has a highest curvature as a to-be-detected point; applying an instrument integrating an X-ray light source and a detector, measuring the to-be-detected point by using an X-ray diffraction theory, and analyzing and calculating, in combination with a sinΨ method, a strain value measured by using the instrument; and calculating, in combination with material property measurement data of the curved surface block material, a residual stress by introducing a curved surface block residual stress calculation model.
