Paper Abstract

Twin-core and polarimetric fiber optic sensors have been embedded in composite plates and used to measure subsurface flexural and compressive bearing strains. Residual thermal stresses have been observed by measuring the change in the twin-core crosstalk with wave-length near the antisymmetric mode cutoff and subsurface crack initiation and growth has been detected with a subsurface twin-core sensor in a pin-loaded bolt hole fatigue test.
