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

l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
