EASI-STRESS Benchmark and validation

EASI-STRESS is a Horizon 2020 project directed at developing validated protocols for residual stress characterization techniques. A specific objective of this project is to produce a range of specimens with which to benchmark high-energy diffraction based techniques against semi-destructive and destructive techniques and computational models. Therefore, there is a need to pursue the measurement of benchmark samples of known provenance which are easily replicable in terms of strict manufacturing tolerances and material controls, as well as residual stress state. The aim of this specific proposal is to measure elastically imposed stress, and plastically imposed residual stress on the first of these reference specimens by synchrotron diffraction.
