measuring method for residual stress

I understand most of method can be used to measure residual stress.
But there is not so much using ultrasonic to measure residual stress. that is why we are looking for it using ultrasonic.
Would you please send us good information how to measure residual stress using ultrasonic?
We appreciate your prompt reply.

best regards
James JOE

Re: measuring method for residual stress
We have had considerable luck using Quasar's resonant inspection technique for detecting unwanted residual stress. It does depend on what it is that you are looking at, however. Please feel free to contact me with additional details, and I can tell you whether or not the Quasar REsonant Inspection method might be applicable.

Re: measuring method for residual stress

: Since about 1980 the Fraunhofer Institute develops ultrasonic and micromagnetic techniques to evaluate stress states of parts and componenents. In total, more than 50 systems are built and in daily use by our customers. Since there are different possibilities to use the ultrasonic and micromagnetic techniques, it is needed to optimize the sensors and the specific technique to the particular case of application.
Please contact me for more information
Kind regards

Please see http://quasarintl.com. There is technical information on the site. Once again, this is not the classical ultrasound testing. It is process compensated resonance inspection testing. I will be pleased to answer any questions you have after you check the site to see if this may be applicable for your needs. Please e-mail me at the above address if you wish for more detailed information.
