Residual Stress Changes in Fatigue. Volume 1. Residual Stress Measurements by X-Ray Diffraction in Notched Test Specimens
Abstract
An experimental setup is described for performing stress measurements on notched test specimens under load using a TEC series 1600 x-ray diffraction system. Excellent results are being obtained for Ti-6Al-4V material, but measurements on 7475-t651 Al are complicated by a texturing problem. Also, some unusual effects are observed during plastic deformation which are not yet understood. The performance of the x-ray diffraction system is found to be quite good in general, but some minor problems are noted.
