Abstract

Structural health monitoring (SHM) is an emerging technology aiming at the on-line diagnosis of damages inside structures during their operation. Successful implementation of SHM allows enhancing the safety and evaluating residual lifetime of structures in service, thus avoiding exorbitant maintenance costs. SHM characterizes various defect-related changes in structures in an online and real-Time perspective, proves itself a promising tool to reduce the risks of structural failure. Among various SHM approaches, the one based on acousto-ultrasonic (AU) waves has become the research highlight due to its appealing advantages like larger monitoring range and high sensitivity to damage. Particularly, guided-wave-based SHM is of great research interest due to its relevance to engineering structures. Development of guided-wave-based SHM solutions typically involves the consideration of three main issues: (1) wave excitation, propagation and acquisition; (2) wave-damage interaction and underlying mechanisms; and (3) SHM systems and damage identification algorithms. This review paper highlights the state-of-The-Art of existing SHM approaches and summarizes some of the recent progress made in the research group led by the author, covering all three aforementioned aspects. Existing challenges and possibilities are discussed.
