X-Ray Residual Stress Measurements in Notched Test Specimens



X-ray residual stress measurements were made in notched test specimens of 7475-T651 aluminum and annealed Ti-6Al-4V in a configuration designed to simulate fatigue testing in a tensile testing machine. An automated and portable X-ray stress analysis system with a position-sensitive proportional counter was used for making the measurements. Sources of error in the measurements resulted from counting statistics, grain size, and preferred orientation in the specimen, and the radius of curvature of the notch. The feasibility of in situ residual stress measurements during brief pauses in fatigue testing is demonstrated.
