Novel Applications of the Deep-Hole Drilling Technique for Measuring Through-Thickness Residual Stress Distributions
TL;DR: In this article, the authors present novel applications of the deep-hole drilling technique for residual stress measurement in components and outline the versatility of this technique for application in complex situations such as residual stress measurements in very thick components, components with difficult access to the measurement location, very large components, and components requiring detailed near surface residual stress distribution.

An integrated approach for measuring near-surface and subsurface residual stress in engineering components
TL;DR: In this article, measurements performed using an integrated center hole drilling-deep hole drilling technique on two components: a butt-welded plate and a rail were compared with th...

Prediction and measurement of residual stresses in cladded steel
TL;DR: In this article, the residual stresses near the interface of a cladded specimen were examined by neutron diffraction, ring core and deep-hole measurements and compared with a nonlinear elastic-plastic finite element analysis.

Residual Stress Measurement within a European UIC60 Rail Using Integrated Drilling Techniques
TL;DR: In this article, an integrated incremental center-deep hole drilling technique was used for residual stress measurement in a new rail measured by using an integrated Incremental Center-Deep Holes (ICD) technique.
