Residual Stress Measurement Tools and Methods: Industrial View of Current Gaps and Opportunities

This paper provides an overview of the types of residual stress that engineers deal with and the tools and techniques available to measure it. It identifies the causes of manufacturing-induced residual stress along with their effects. It summarizes the practical aspects of a wide range of measurement methods, including hole drilling, layer removal, contour, lab XRD, and synchrotron analysis. It assesses current challenges and gaps in determining stress in relation to stress type, stress component, microstructure, specimen geometry, materials type, and measurement location.
