Abstract

This paper presents novel applications of the deep-hole drilling technique for residual stress measurement in components. The results outline the versatility of this technique for application in complex situations such as residual stress measurement in very thick components, components with difficult access to the measurement location, very large components, components requiring high spatial resolution, and components requiring detailed near surface residual stress distribution. The deep-hole drilling measurements were compared with results obtained using other measurement techniques. Excellent agreement was found between the results.
