stress measurment by eddy current

i'm a student of mechanical engineering in tehran polytechnic university.
i wanna know if it is possible to measure the residual stress
by eddycurrent.if it is possible please show me some refrances
about this matter.
i want to plan some experiments on this field.please help me in this way.
many thanks

Re: stress measurment by eddy current
"Wanna" know?!

Residual Stress may be measured using electromagnetic methods, but is is quite a difficult problem. I do not have references to hand, but do a search for work by David Buttle at AEA Technology. He developed the MAPS system which, to my knowledge, is the only such non-destructive method that can measure absolute stress.

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
