I have a problem with the calculation of the torsional rigidity of a spline shaft.
Using the static analysis, I selected a fixed surface, then I want to apply the torque on the spline (in order to evaluate the angular deformation and the torsional stiffnes as ratio between Torque and theta).
I can I apply the torque? Do I have to select torsion, and then select each lateral surface of every thooth? If I do so the value of the torque will be split on every thooth?
Please help a poor student
