So I am planning on doing an FEA for a rotational component as part of university project. I am fairly confident about the analysis itself, meshing, convergence, etc.. I feel I am capable of setting up an accurate model. However, I need to validate my study with a simple preparatory FEA which can be verified by hand. Any ideas on how this may be accomplished? My first thought was to use beam torsion equations for a simple cylinder, but the model is then too simple and will not be sufficient. I am not sure if being verified by hand means using matrices, etc.
