The use of ultrasonic nonlinearity for damage detection and monitoring of structures has attracted growing attention. Interaction of guided waves with contact-type damage, such as debonding, is one of the major sources of ultrasonic nonlinearity. This paper investigates higher harmonic generation of Rayleigh waves in FRP-retrofitted concrete structures due to debonding between FRP and concrete. In this study, propagation and scattering of Rayleigh wave are simulated using a three-dimensional finite element model. The numerical simulations of both linear and nonlinear Rayleigh wave are validated with experimentally measured data. There is very good agreement between numerical and experimental results. This paper also investigates the scattering directivity patterns of second and third harmonics of Rayleigh wave. The results provide physical insights into nonlinear Rayleigh wave generated by debonding between FRP and concrete. Overall, the findings of this study can further advance the damage detection methods using the nonlinear Rayleigh wave.

“…They showed that the second harmonic amplitude is more pronounced for low compressive stress applied to close the crack. Zhang et al [47] showed that the higher harmonic generation of Rayleigh wave could be used to detect surface scratches in glass. They investigated the effect of the surface scratches in relation to the characteristics of the higher harmonic generation of Rayleigh wave.…”

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.

“…V. M. Ushakov etc [5] use ultrasonic Rayleigh wave time delay method to detect surface crack. Zhang Jianfeng etc [6] use nonlinear Rayleigh wave to detect the width of the glass surface scratches. Due to the interface debonding damage close to the free surface, using related parameters of Rayleigh wave to detect debonding damage should be feasible.…”

Abstract-This paper studied how to use the variation of the dispersion curves of Rayleigh wave group velocity to detect interfacial debonding damage between FRP plate and steel beam. Since FRP strengthened steel beam is two layers medium, Rayleigh wave velocity dispersion phenomenon will happen. The interface debonding damage of FRP strengthened steel beam have an obvious effect on the Rayleigh wave velocity dispersion curve. The paper first put forward average Euclidean distance and angle separation degree to describe the relationship between the different dispersion curves. Numerical results indicate that there is a approximate linear mapping relationship between the average Euclidean distance of dispersion curves and the length of interfacial debonding damage.
