Quantification and uncertainties in residual stress measurement

Measuring the residual stress levels is essential for validating finite element modelling efforts and developing efficient stress mitigation strategies. But a measurement is never better the uncertainty you can assign to it. In this tutorial, we will discuss how residual stress levels are measured using different techniques - and which uncertainties and error bars that should be associated with the most common residual stress measurement techniques used in industry. The presentations will include benchmark studies and round robin proficiency testing and deliver a status of the standardisation efforts in Europe and the US.
