Structural integrity monitoring, to anticipate and prevent failure, is a multi-billion dollar effort worldwide. Detailed assessment of the capability of fibre Bragg gratings to measure strain profiles along the grating length, i.e. intragrating sensing, and thereby detect structural ?hot spots? before failure is essential for effective systems. They will be used to determine strain gradients similar to those found in common problem areas, such as the tips of elliptic notches and disbonding at the ends of composite joints. Additionally, grating refractive index profiles will be characterised using imaging techniques, to assess performance and possible changes to gratings after prolonged use.Read moreRead less
