stress field

Hi all!!

If there is a specimen subjected to any kind of loading, i would like to find out how much load was applied in that specimen (most likely a specific point of interest) by ultrasonic technique. is it possible?

please provide me any advise.

thanks very much

Re: stress field
Hello Young...

What was the specimen
type, dimensions, wall thickness, etc...? There may be a way to make that determination with AE.

Re: stress field
Dear Young

as Kris already wrote, AE may help you by using the Kaiser-Effekt: if you (mechanically) load and unload a sample, then reload again you will not get AE unless you exceed the previous load level.
This is not generally true under all circumstances, but is used in different applications.

regards
Jens
