Radial Surface Waves

Does anyone have some references about using radial surface waves
from short focused transducers to detect surface and near surface
defects and material property variations?
Thanks in advance for your help.

Mr. Sebastian Gripp of our organisation has realized an industrial solution for surface testing of contoured turbine discs applying a specific rayleigh wave probe. The corresponding paper has been presented at the WCNDT in Rome last fall.

Re: Radial Surface Waves Mr Gripp's paper is available at:
Surface Crack Detection Using Rayleigh Waves - in immersion: A Novel Application of a Known Principle

Also I would like to take the opportunity to introduce a problem of the email address used in the forum message.
Albrecht Maurer used in his message the email address "albrecht_maurer@nukem.de",
but his Member Profile is registers with the email address "Nutronik@Nukem.de".
The system can set Profile and Exhibitors links only according to the registered Forum Profiles.

Mr. Maurer's Profile: http://www.ndt.net/wshop/profile/profiles/123.htm
NUKEM Nutronik GmbH: http://www.ndt.net/exhibit/stand/15_ky.htm

That means you shall use for forum messages always the email address of the profile.

Best regards
Rolf Diederichs

.I hope this will clarify the points. For past 3 years we are working on developing sensors and system for surface and subsurface characterization of materials in terms of surface velocities and amplitude information and we have a success. We have full facility at University which one can take advantage. The University is McMaster in Hamilton, Ontario or at Fallon Ultrasonics Inc in Hamilton.
