Paper Abstract

Optic fiber Bragg grating sensor is a new type of sensor, which plays an important role in structural healthy monitoring. When the optic fiber Bragg grating sensor is embedded in the structure or adhered to the structure, there is a strain transferring course between structure and sensor for the existence of interlayer. Important factors that affect the strain transferring are conducted on the base of existent theory in this paper. The influencing parameters are the length of the sensor, the thickness, Young's modulus and Poisson's ratio of interlayer. At the same time, different influencing factors on strain transfer rate are discussed in detail. Some useful conclusions are developed, which provide a theoretical basis for future researches and designs.
