Hi All,
I am looking for a formula to describe the stress in the centre of a circular plate, stiffened with a small pipe. Something like added section.
Roark formula 9(a), from table 11.2 is quite good if i compare the results with FEA, but that is just a flat circular plate.(without the ring...)
The ring stiffens the plate, so the plate will have less stresses at the centre.
Roark has something like underneath, but it doesn't describe the stress at the centre of the plate.
If I use Roark 9b here, the stresses are way off, compared to FEA.
Can somebody help me with a formula (roarks maybe?) describing the stress at the centre of the plate, where the plate is stiffened?
I am looking forward to hear from you!
