Source for plastic moduli ?

(OP)
Looking for a source of plastic moduli of open circular cross-sections. I looked in Roark's, but alas.
Specifically of circle sectors (angle > 180) and circle segments (larger than half a circle)
Anyone out there can point me in the right direction?

Good source for verification of results.
I'm developing a program that needs plastic moments, so am looking for formulas.
