FE reports as reference and "Mesh safety factor"..
FE reports as reference and "Mesh safety factor"..
(OP)
Hello All,
When doing a Finite Element study (of a steel component for example), suppose that we have a very good mesh and a very good model, I want to know if there are safety factors related to the finite element study to measure the difference of the results in comparison of the reality?
I would like to know also if there are complete finite element studies (reports) that have served in building a real part (that exist…not just a study for “fun”) that can be seen and serve as a reference for further studies?
Best Regards.

2nd question: You might want to search for so-called benchmark problems or studies. NAFEMS published studies are a good reference.

In industry where FE analyis is carried out you won't find out that a study has been done for 'fun', though I sometimes wonder.

The problem of benchmarks is that they are based (the result is compared to) on theoretical/analytical calculations.
So, if a mechanical part is designed to resist a certain load and to remain ender certain displacements (deformed shape) limits by the FE methods, it will really resist or not? In some cases, was it certain surprises (not resulting from incorrect modelling, meshing…)?
