Investigation on Characteristic Variation of the FBG Spectrum with Crack Propagation in Aluminum Plate Structures

In order to monitor the crack tip propagation of aluminum alloy, this study investigates the variation of the spectrum characteristics of a fiber Bragg grating (FBG), combined with an analysis of the spectrum simulation. The results identify the location of the subordinate peak as significantly asso...
