Guided wave measurements based on dual PZT and FBG sensors in aluminium plate with simulated damage

The upload contains data files for measurement on aluminium plate 1000 mm x 1000 mm x 1 mm for the case of PZT actuation (in the middle) sesing 250 mm from actuation by pairs of 2xFBG and  2xPZT sensors (located as a pairs located on the left and right sied of actuator). Each pair contains of the sam sensor on the top and bottom surface. Frequencies 50-250 kHz, excitation: 5 cycles of sine modulated by Hann window. Four cases of simulated damage was investigated. Detailed description could be find in "Readme" file in "Measurements.7z" achive attached as well as publications related to this dataset:
