Hoop stress in an oval thick walled pipe

Hoop stress in an oval thick walled pipe

(OP)
Hello engineering friends,

I'm looking for a method to calculate the hoop stress in an oval thick-walled pipe. Other than performing a FEM that is. I came across this paper (http://www.acwhyte.fsnet.co.uk/ovalpipepaper.htm), but as far as I gather this refers to thin-walled pipe work only.

Thanks!

RE: Hoop stress in an oval thick walled pipe

Appendix C.3.4.6.4 of PD 5500 has stress calculation methods for deviations from design shape. Included is a shell ovality equation. It doesn't seem to place any limits on the amount of ovality either.
