“…In this study, only the deformations Fig. 4 shows a comparison of the A0 Lamb wave group velocity dispersion curve calculated by the FE simulations and analytical results, which is based on the Mindlin plate theory [48]. The results show that there is very good agreement between the FE calculated and analytical results.…”

“…Guided waves are mechanical stress waves propagating along the structures and guided by its boundaries. Lamb wave refers to guided wave propagates in plates with wavelength larger or of the order of the plate thickness [8]- [11]. In the last two decades, Lamb wave has been widely used for damage detection of plate-like structures [12]- [15].…”

The proposed method requires a network of transducers that are used to sequentially scan the CFRP-retrofitted reinforced concrete structures by transmitting and receiving Rayleigh wave. The nonlinear feature used for the debonding detection is second harmonic generation due to the interaction of Rayleigh wave at the debonding between the CFRP and concrete interfaces. A damage image reconstruction algorithm is proposed to provide a graphical representation for detecting and locating the debonding in the CFRP-retrofitted reinforced concrete structures. In this study, experimental case studies are used to demonstrate the performance of the proposed debonding detection technique. A transducer network with four piezoelectric transducers is used to actuate Rayleigh wave and measure the second harmonic wave in the experiments. The results show that the proposed debonding detection technique is reliable in detecting and locating the debonding in the CFRP-retrofitted reinforced concrete structures.

“…The importance of Structural Health Monitoring (SHM) in engineering field is currently undisputed, and benefits of SHM systems have been discussed in many papers [1]- [4]. SHM systems based on ultrasonic guided waves, such as Rayleigh wave [5] [6], Lamb wave [7], [8] and torsional wave [9]- [10], have attracted attention over the past two decades [12]- [14], and different damage detection techniques using linear guided wave were developed and deployed across many industries [15]- [17]. One of the main objectives of the SHM systems is to provide the information in a real time, which is required for structural life prognosis and maintenance scheduling.…”
