Abstract The applicability of embedded fiber-optic sensors for the determination of fracture parameters is demonstrated. A Mach-Zehnder interferometric setup is used and mode-1 stress-intensity factors are obtained by embedding single-mode fibers in single-edge-notched specimens fabricated from Plexiglas. Optical fibers are embedded in-plane to measure axial strains at various depths and also in the transverse direction to measure the transverse strains, from which stress-intensity factors are determined. In both cases the experimental results compare well with the theoretical predictions.
