minus-squareSuccessful_Try543@feddit.delinkfedilinkarrow-up1·7 months agoThat’s a valid approach, yet today, experiments are usually on a smaller scale.
minus-squareDonkter@lemmy.worldlinkfedilinkarrow-up18·7 months agoActually, a bridge like this is generally considered simple enough not to require FEA. Calculating it theoretically using trusses should be enough to make it. I’m sure FEA is still done but only because it’s easy and cheap.
How to determine the elastic tensor without any FEA tools?
Experiments and theory.

No, that’s the FEA part.
