Maintenance of structures is important in many areas of aerospace, civil and mechanical engineering to ensure structural integrity and safety. There exist a variety of different Non-Destructive Testing (NDT) methods used for damage detection. The majority of theses methods were developed in the 1960s. Recent years have shown a range of new damage detection techniques and sensing technologies. These methods allow for global, on-line monitoring of large structures and fall into Structural Health Monitoring (SHM) area. They are capable of achieving continuous monitoring for damage also thanks to the application of new sensors. Damage monitoring systems which use smart sensor technologies are concerned with a design philosophy directed to the integration of actuators, sensors, and signal processing. This approach will be demonstrated using application examples from crack detection in metals and impact damage detection in composites. A variety of different damage detection methods, sensing technologies and signal processing techniques will be presented.
