N2 - The need for reliable use of Non-Destructive Evaluation (NDE) tools in Structural Health Monitoring (SHM) applications is driven by the importance of reliable detection of early warnings of incipient damage and of robust separation of such information from the influence of the operating environment. To this aim, a Novel Optico-Acoustic Sensing System (NOAS) is presented herein combining the principles of Acoustic Emission (AE), Guided UltrasonicWaves (GUW) and Digital Image Correlation (DIC). The simultaneous use of volumetric and surface inspection techniques provides a cross-validated monitoring approach capable to identify damage pre-cursors and to track progressive damage development. In this paper, emphasis is given in aerospace materials and substructures in which the NOAS has been employed to identify dominant failure mechanisms in laboratory specimens, and to determine parameters sensitive to both damage initiation and subsequent development in structural components. This combined approach shows promise for reliable and in situ detection of important damage sources, which is crucial in designing robust SHM systems suitable for on board aerospace applications.
