Hello everyone,
I am modeling a stiffened composite plate; siffeners are made in composite too, with a different stacking sequence.
I was wondering which could be the best element type for modeling the stiffeners: shells made with my laminate, or beams with laminate's equivalent properties?

Thanks for your support!
