title = "Guided wave technique for non-destructive testing of StifPipe{\textregistered}",
abstract = "The newly-developed StifPipe{\textregistered} is an effective technology for repair and strengthening of existing pipes and culverts. The wall of this pipe consists of a lightweight honeycomb core with carbon or gla{\ss} fiber reinforced polymer (FRP) applied to the skin. The presence of the hollow honeycomb introduces challenges in the nondestructive testing (NDT) of this pipe. In this study, it is investigated if guided waves, excited by PZT (Lead ZirconateTitanate) transducer can detect damages in the honeycomb layer of the StifPipe{\textregistered}. Multiple signal proce{\ss}ing techniques are used for in-depth study and understanding of the recorded signals. The experimental technique for damage detection in StifPipe{\textregistered} material is described and the obtained results are presented in this paper.",
