| Abstract: | In this paper, a direct method based on the Sandifer and Bowie theory was derived to take hole-alignment error into account in residual-stress measurement. The principal stresses and their orientation are calculated directly from this method when the relaxed strains, hole diameter, eccentricity and orientation are known. It is more convenient to use than other iterative methods. |
