An experimental study is conducted to evaluate the performance of different fiber optic sensors in fracture mechanics applications. A variety of measurement systems, using optical fibers as sensors, were used with simple fracture specimens to determine static and dynamic stress intensity factors and also the location of the crack. The values thus obtained, were compared with theoretical solutions or results obtained from other experimental techniques. The results show the successful application of fiber optic sensors both in attached and embedded configurations, and thus open up the possibility of using them in a host of applications where conventional sensors prove inadequate. Besides describing the various sensors and the results obtained from them, this paper emphasizes the advantages associated with certain configurations of the fiber optic sensors and points out the drawbacks with others.
