- double0jimb0 2y agoFEM runs on the same math and theories those bridges were designed on on paper.
- meindnoch 2y agoAnyone can design a bridge that holds up. Romans did it millenia ago. Engineering is designing a bridge that holds up to a certain load, with the least amount of material and/or cost. FEM gives you tighter bounds on that.
- drpossum 2y agoThe average age of a bridge in the US is about 40-50 years old and the title of the article has "80 years of FEM". https://www.infrastructurereportcard.org/wp-content/uploads/2017/01/Bridges-Final.pdf https://www.infrastructurereportcard.org/wp-content/uploads/... I'd posit a large fraction were designed with FEM.
