Abstract
The dynamic characteristics of a structure can be obtained by means of non-invasive techniques, such as digital image correlation (DIC), from the measurement of displacement fields. This work proposes the identification of the natural frequencies and vibration modes of a thin plate by the stereo correlation technique. In a first step, a bench experiment assisted by the digital image correlation technique was carried out with the application of a dynamic load on the end of the tapered flat plate. Then, the Dynamic Mode Decomposition (DMD) technique was applied from the displacement measurements obtained experimentally. This computational method allowed predicting the frequency of 9.905 Hz for the first bending mode.
