Paper Abstract

The potential for using fiber Bragg grating rosettes for the location of ultrasound sources in anisotropic structures is discussed. Anisotropic propagation of Lamb waves in a carbon fiber composite plate has been investigated using two approaches. Firstly, a finite element model of the displacements/strains produced by the wave was developed and, secondly, in-plane ultrasonic strain mapping was carried out, utilizing the directional properties of FBG sensors. The possibility of designing FBG rosette configurations for use on anisotropic structures is discussed in light of these results.
