### Abstract

An analysis is presented to measure the residual shear stress as well as the normal stresses in the tube wall. Residual stresses are determined by removing material from the exterior of the tube, while measuring the resulting strains on the interior of the tube using rectangular rosette strain gages. An electrochemical machining process is utilized to reduce the cross-sectional area of the tube due to its constant mass removal rate and ease of application in obtaining data to calculate the residual stress distribution using the Sachs technique. Since the tubes under investigation exhibit cylindrical elastic anisotropy, equations developed by Voyiadjis, Kiousis, and Hartley ('analysis of residual stresses in cylindrically anisotropic materials') are used to determine the circumferential, longitudinal, radial stresses as well as principal stresses and their direction as a function of tube wall thickness. Finally, the residual stress profile throughout the wall of as-received tube is compared to that of the tube annealed at 500 degree C for one hour.
