A chirped fiber Bragg grating was used to measure the non-uniform strain profile of a notched aluminum specimen usedto simulate a cracked structure. The specimen was subjected to tensile tests that produced regions of non-uniform strainnear the notches. Analysis of power reflectance spectra from the grating, through the use of an integration method,enabled the strain profile near the notches to be determined. Unlike other intragrating sensing methods, this method didnot require a disturbance hypothesis to be postulated. The strain profile results from this intragrating sensor were inreasonable agreement with predictions from modeling conducted using the finite element method.
