Is there any well-established benchmark to test the validity of a finite element analysis, i.e. FEA? For example, a 3D model with specific loading and boundary conditions. Along with the expected results for stress or strain.
Scientific journal papers could use such a benchmark for validation. Just wondering if there is such a standard benchmark.
Maybe one option is a simple 3D structure with a known structural response like this one taken from that reference:
As @TomášLétal pointed out, probably a set of verification tests are needed to cover a range of aspects.
According to comments and posts, these are the options:
- Simple 3D structure with known structural response.
- Doing a modal analysis, as they apparently do in the automotive industry.
- Compare against real experimental results.
- ANSYS or ABAQUS Verification Manual.
There are simply-supported structures along with their hand calculation analysis here: https://github.com/calculix/CalculiX-Examples/tree/master/NonLinear/Sections
They could possibly be verified benchmarks.
