“…In contrast, if the direction of the loading was transverse as in three-or four-point bending, the sensors were usually embedded in locations away from the neutral plane through the depth of the beams [64, 69, 78-80, 82, 83, 85]. Although a quasistatic loading was also used [56,73,98], the rectangular plates were used mainly in conjunction with an impact loading [32-43, 45, 47, 48, 50, 52, 53, 55, 59, 60, 63, 65]. Thus, the sensor locations were away from the neutral plane of the plates just like the beams under a quasi-static transverse loading.…”

A state-of-the-art review is presented regarding the research and development of in situ fibre optic damage detection and assessment systems (FODDAS) embedded in fibre-reinforced composite structures. Representative individual fibre optic strain sensors and distributed sensor networks are briefly described. A major emphasis is placed on their capabilities for detecting damage, determining damage location and assessing the nature of damage, arising primarily from specific events such as impacts or quasi-static stress overloads. The main features of such systems as custom-built and structure-specific units with minimal human involvement are highlighted. Issues that could affect the validity of the performance of such strain sensors are discussed. Fracture and non-fracture of fibre optic sensors are identified as two fundamentally different approaches for damage detection and their primary features are discussed in relation to location determination and evaluation of the nature of damage. The major advantages and limitations of each approach are discussed. Directions and areas of potential future research in the development of related FODDAS are highlighted.
