Calculate the size of the arbitrary cracks using TOFD method.

Dear NDTnet Readers;
I would like to establish a TOFD mathematical model for
calculating the size of defects which position and
orientation are not vertical to the surface.At the moment
I am finding difficulties to calculate the bottom tip crack
angle lying parallal with the surface.
I very much appreciate any information (Book, Jouranl, etc.)
from anyone.

Kind Regards

Re: Calculate the size of the arbitrary cracks using TOFD method. Dear Shamal,

I am very familar with the Time of Flight techniques using Tip Diffraction. I teach these technqiues along with ID and OD Creeping Waves and BI-modal Methods. I have written a handbook on these techniques. See NDT.Net library.

I need to understand better your question. I train inspectors with Tip Diffraction to read the flw depth directly from the UT screen.

Are you trying to determine the angle of the crack if not vertical but oriented?

I look forward to addressing your questions.

Thanks,

J. Mark Davis
