Flat bottomed v side drilled

I am trying to dig up some information comparing the responses of side-drilled and flat-bottomed hole standards. At the moment, I am looking for comparisons of different diameter side-drilled hole amplitudes. I know I can do this experimentally, but it benefits me most in my discussions if I have something in hand that is published already.
Thanks in advance for anyone that can share this information!

Look up Ed's Article on the Ermolov equations:

One of the highlights of the site IMHO

The relationship between flat-bottomed hole and side drilled hole has been intensively discussed in the 70th of the last century by the Subcommission Vc (Ultrasonic inspection of welds) of the IIW (International Institute of Welding) and ended up with the introduction of a simple formula in EN standards determining the diameter of a flat bottomed hole in dependence from the diameter of a side drilled hole for the same distance, wavelength and amplitude. You may find this formula within the EN standard:

Hi,
I can suggest start drill hole with 15mm to 25mm diameter surface area.Flat bottom drilled and side drilling hole can measured with drilling tools and working equipments.
