Fiber Bragg Gratings Array for Structural Health Monitoring

Abstract:

Impact event monitoring and source location in some critical structures. The current work evaluated the feasibility and limitation of using fiber Bragg gratings (FBGs) for this purpose. Impact testing carried out on a cold rolled aluminum plate showed that impact event monitoring with the FBGs is feasible with the current intensity modulation interrogation method. Source location is successful at part of the impact location but not at the others. This phenomenon is caused by the complex wave propagation pattern on the plate so that differently oriented FBGs receive the signal from the same impact at different time.
