In civil engineering, structural adhesive bonding is increasingly used as an assembly method for the reinforcement or rehabilitation of old structures by composite materials. However, the presence of defects within the bonded joint may affect the effectiveness of the assembly, and their detection is still an issue. The purpose of our study is to use the acousto-ultrasonics (AU) approach to detect, identify and assess the severity of all types of defects within adhesively bonded joint.
