Hey everyone, hoping someone can point me in the right direction with a deflection question.
A pressure vessel I'm working on needs to be pressure tested before it can be shipped out to the customer, so I'm having a large plate cut to match the flange. The opening is about 1500mm in diameter. It's pretty low internal pressure (less than 1MPa).
I've performed FEA and I know the deflection in my plate is next to nothing (AS1210 says it has to be at least 6mm thick), but the client wants to see the calculations to prove this (you'd think the printed FEA results would be enough).
Is there a way of finding maximum end cap deflection based on 'normal' information I'd have or can calculate?
Is there something similar to the standard beam deflection formulae for round discs?
Thanks very much for any pointers!
