Capt Kenny,

"Can anybody point me to where I can find a copy of the paper <“Stress Indices for Piping Elbows with Trunnion Attachments for Moment and Axial
Loads,” by Hankinson, Budlong and Albano, in the PVP Vol. 129, 1987.> as quoted in the CAESAR II users guide".

Try a library or IMechE in London where you will be charged a few pence for a copy. You shouldn't need more than a sedative for the sporran.
