Re: about dispersion curve tracing
Hi Amir,

I assume you are after dispersion curves for ultrasonic guided waves.

Are you after commercially available software? In which case try this link for a programme called "Disperse":
http://www.imperial.ac.uk/ndt/public/productservice/disperse.htm
You can download a demo version and have a look.

If you are planning to write your own code for tracing dispersion curves or want to use FE modelling, it would be good to know what structure you want the dispersion curves of in order to point you in the right direction - there is a large number of papers on this subject.

Regards,
Tom
