Abstract
Sophisticated measurement methods are currently used extensively to determine the
residual stresses in materials. The capabilities of the Hole-Drilling Method, Debro-30
Ultrasonic System and Digital Shearography to determine residual stresses have been
explored. The accuracy of these techniques in measuring residual stresses in mild steel
specimens is thoroughly examined and discussed. The results obtained from the
experiments are consistent with the expected outcomes. Related literature review,
experimental procedures, results and their discussion have been outlined. It is hoped that the
information provided in this thesis will be of importance to end users, especially engineers
and technologists who use these non-destructive methods to evaluate residual stresses in
components and materials.
