Abstract

Abstract Based on the theory of free vibration of a thin plate, the acoustic-optical fiber NDE technique is proposed for the detection of interfacial debonding in FRP-retrofitted structures. A focused sound beam generated from a variable frequency loudspeaker source can be controlled to form a local vibration field at the surface of an FRP-retrofitted structure. Local vibration anomalies caused by interfacial debonding in the structure can be measured by the surface-mounted optical fiber interferometer, and thus, interfacial debonding can be detected, mapped, and quantified. Based on the results from both numerical and experimental studies, the feasibility of interfacial debonding detection in FRP-retrofitted structures with the proposed technique is demonstrated.
