N2 - Fiber-reinforced polymer (FRP) retrofitting is a widely adopted strategy for enhancing the structural performance of concrete beams due to its ability to impart increased strength and durability. However, FRP retrofitted structures are susceptible to various damage mechanisms, with debonding being a critical issue. In this context, non-destructive testing (NDT) techniques play a crucial role in assessing and monitoring the structural health of FRP retrofitted concrete beams. Among these techniques, the application of the nonlinear guided wave technique emerges prominently as an efficient and effective approach. The nonlinear guided wave technique distinguishes itself for its inherent baseline-free characteristics and exceptional sensitivity to even minor damages. This feature set positions the nonlinear guided wave technique as a promising method for achieving accurate and precise debonding detection in FRP retrofitted concrete beams. The study delves into the challenges associated with debonding and underscores the advantages of utilizing the nonlinear guided wave technique as a standalone NDT method. This paper exclusively focuses on the application of contact acoustic nonlinearity (CAN) for debonding detection in FRP retrofitted beams. Through extensive numerical simulations, various models are considered, incorporating different debonding dimensions and through-thickness locations. The numerical results demonstrate the capability of the nonlinear guided wave technique to accurately detect debonding, offering a promising approach for structural health monitoring. In summary, this paper not only sheds light on the exclusive use of CAN but also provides a nuanced understanding of the interaction of guided waves with damages, enhancing our insights into the phenomena associated with CAN. The research uniquely contributes to our comprehension of the effectiveness of nonlinear techniques, specifically CAN, in contrast to traditional NDT methods.
