Low cost wireless fatigue crack monitoring system using RFID arrays

Metal and reinforced concrete (RC) structural systems are major components of our transportation systems, and cracking of the RC material is an intrinsic material problem due to small tensile strength under cyclic loading. The effect of cyclic loading could be more drastic in metal structures due to fatigue because fatigue may induce progressive and localized structural damage, leading to unexpected sudden failure below the yield stress limit. An efficient means for closely monitoring cracks in structural members is required to provide indicators to enable timely maintenance for better performance and elongated service life. Recent advances in the radio frequency identification (RFID) based Wireless Sensor Networks (WSN) offers various advantages to the traditional sensing technology including cost effectiveness, convenient installation, and easy scanning using any inspection vehicles in services. The WSN-RFID can provide a means to provide convenient data and information to monitor fatigue-induced cracks of metal structures with low cost, convenience, and time efficiency. Therefore, the goal of this project is to create a transformative RFID-based technology, which can determine the existence, location, and severity of fatigue cracks with very low cost to secure Connecticut’s steel bridges and metal transportation systems.
