Use of FEA
Use of FEA
(OP)
How often do the professional engineers on this site use "real" FEA, meaning not the code checking portion of RISA or STAAD, but rather von mises stress contours, as opposed to hand calculations, for somewhat complex situations. Is it worth it for a new engineer to use some of these programs without having taken the theoretical FEA classes at university? I've found that's it's useful to validate my hand calcs when there is no clear code specification for my given project.

And yes...I do check von Mises and other stress variations as necessary; however, von Mises stress distributions in beams is not codified.....it is another tool for us to evaluate.

I use FE fairly frequently for stability and dynamic analysis. For example, I used a shell model with nonlinear analyses to predict the strength against a buckling mode like lateral-torsional buckling, but with unusual boundary conditions.
I do not tend to use FE for strength of plates or slabs in two-way bending. We don't usually go by first yield, and I don't want to do a material nonlinear analysis during design, so I'm more likely to use yield line analysis.

27128 What program are you using for these analyses?

If you can take an FEA class, it's probably worth it as you will (hopefully) learn some fundamentals. Hopefully the guy teaching it will have practiced and he will have useful advice.
