Residual stress is a common cause of failure in aerospace components, as it leads to crack formation; to protect against that, shot peening is used to increase the tensile strength of steel. State-of-the-art non-destructive methods, however, cannot adequately assess the quality of shot peening. This project will revolutionize residual stress detection in steels using a novel magnetic method that has been proven at TRL3.

We are looking for partners in the following areas:

- Private companies in the aerospace, automotive or manufacturing industries, who can provide samples for validation and field testing trials.

- Universities / research institutions who can characterize residual stress in steel parts using proven methods, such as x-ray diffraction

The project leader is the inventor of this method, and has a proven track record in academia and industry.
