Detection and safety assessment of bonding defects in architectural decorative surface layer based on the variation of vibration acceleration amplitude
Bonding defects in the architectural decorative surface layer can cause the finish layer to detach, posing a significant threat to urban public safety. To minimize the risk of finish layer detachment and ensure its safety, this study presents a novel non-destructive testing technique that detects bo...

| description | Bonding defects in the architectural decorative surface layer can cause the finish layer to detach, posing a significant threat to urban public safety. To minimize the risk of finish layer detachment and ensure its safety, this study presents a novel non-destructive testing technique that detects bonding defects in the decorative surface layer by analyzing variations in vibration acceleration amplitude. The experimental design investigated how bonding strength, hollowing area, distance between excitation and pick-up points, pick-up point position, and excitation force affected vibration acceleration amplitude under different bonding defect conditions. Results indicated that as bond strength increased, vibration acceleration amplitude decreased. Specifically, when the bond strength diminished by 83 %, there was a 19,611 % surge in the vibration acceleration amplitude. Additionally, variations in vibration acceleration amplitude were highly sensitive to bonding defects. Notably, when the area of the hollowing expanded by 800 %, the rate of increase in vibration acceleration amplitude escalated by 7,553 %. Under the same conditions, vibration acceleration amplitude increased with a larger hollowing area and decreased as the distance between the excitation and pick-up points increased. As the pick-up point shifted from the hollowing center to its edge and then to a non-hollowing region, the vibration acceleration amplitude decreased accordingly. When the pick-up point was located within the hollowing region, the measured vibration acceleration amplitude was significantly higher than in a well-bonded scenario. |
