DATA & FILE OVERVIEW
--------------------

This dataset contains the numerical data used to produce the Figures 4-12 of the publication, some of which are divided into sub-figures from (a)-(c). 
-It is separated into 16 files generated in Microsoft Excel (.xls), one for each sub-figure. 
-Each sheet in the individual .xls files corresponds to one of the lines that is shown in the figure or a part of the scatted data in Figure 8 and 9a/9b.
-A description is available in each sheet, that refers the data to the corresponding line in the figure.
-In each sheet, the x- and y- data are stored as a 2-3 column matrix, where the first row always corresponds to the x-data and the second and third to the y-data.


In the ZIP file the data is organised as follows:
- fig4.xls
- fig5a.xls
- fig5b.xls
- fig6a.xls
- fig6b.xls
- fig7a.xls
- fig7b.xls
- fig8.xls
- fig9a.xls
- fig9b.xls
- fig10a.xls
- fig10b.xls
- fig11a.xls
- fig11b.xls
- fig11c.xls
- fig12.xls

--------------------------
METHODOLOGICAL INFORMATION
--------------------------

Description of methods used for collection/generation of data: The data was generated from numerical simulations in COMSOL Multiphysics 5.4 by solving the free Vibration of stiffened platesfor different parameters

Methods for processing the data: The obtained Vibration data from COMSOL was processed in MATLAB to generate the Sound Radiation data via Rayleigh Integral method.
