I will use only Flexible as I am interested in deformations, stresses, and strains in all solids.
I am analysing two different bridge girders (concrete and steel):
- Concrete which have thick girders (the image shows a cross-section) (vertical elements are not piers, are girders (beams)).
- Steel which have thin cross sections
In order to use shell elements, should I use them in both typologies or only in the steel one as I am dealing with thin elements?
