UT Curvature Correction

I’ve got a question for you if you don’t mind. I’m taking a test and need to report the flaw location with curvature correction. The Outside Diameter of the plate is 205.22 inches with a thickness of 11.44 inches. When I record a flaw from the Outside Diameter with a given angle say 46 degrees. The particular software I’m using doesn’t correct for Curvature. So if I record a flaw at a certain depth from the Outside Diameter I then have to give the position inside the metal. So is there a formula that I can use to perform this calculation? I hope this makes sense. If you need more information you can email me.

Just make a drawing to scale and figure out.
The other option to use trignometry

Paul,

Thanks for taking the time to create this formula! We we say “sound path”, I’m calibrated in depth not metal path. Will the formula still work entering the depth in the material instead of metal path?

Thanks again,
Richard
