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

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.

The measurement campaign will be explained in details in a journal article which is in preparation. The link to the article will be updated. 

The measurements were conducted under the research related to grant agreement no. 2020/39/B/ST8/01753 in the frame of the OPUS project entitled: "Study of elastic wave mode sensing and separation using FBG sensors for structural health monitoring ", supported by the National Science Centre, Poland.
