This study focuses on the connection between damage progression and non-destructive testing techniques to evaluate the feasibility of these techniques for structural health monitoring. For this aim, three different techniques, acoustic emission (AE), digital image correlation (DIC) and infrared thermography (IRT), were selected deliberately due to their focus on detecting the three different manifestations of energy that originates from damage. Feasibility of these techniques were assessed on carbon fiber reinforced composites with two different stacking sequences under static loading conditions. Static loading conditions were selected to have less noise in the AE and the IRT data. Moreover, two different stacking sequences provided a better understanding on the response of non-destructive testing techniques.
