Lamb waves and dipersion curves in plates

Please login with a confirmed email address before reporting spam

Hi,

i'm trying to solve the paper of pablo Gomez about Lamb Waves and Dispersion Curves in Plates. I made the first part of this work, but i didn't know how can i do the rest. Especially how could i make a fourier transform (FFT) of the displacement to get the frequency - k(wave number) or frequency - group_velocity representations?
I read in many papers that the lonly way to do this, is to write a matlab code .. but i really dont have no idea how it works.
In Comsol version 5.2 there already a study step : time to frequency fft , i try it but still i dont know how can i plot the dispersions curves of lamb waves!
it would be very nice if someone had an expereince with the same subject and can help me to solve this paper.

Best Regards
Mahir
