How to apply a moment on a cylinder?
(OP)
I wonder how to apply a bending moment in the center of a cylinder.
I guess some form of coupling and connector have to be made, but dont know how to do it?
The moment should be applied in the axissymmetric axis.
Please help!

RE: How to apply a moment on a cylinder?
I think you are talking about a torque and not moment. In order to do this you could define a reference point and link the point to the nodes on the circular surface by kinematic coupling. Then the torque could be applied directly to the reference point. It will be transmitted to the required nodes through the coupling.

Only the rotations are wanted to be equal, but there comes up an error when trying to solve the problem with these conditions.
Is it possible to solve the problem with some kind of connector? Wires are needed, how to apply these and how to apply the moment?

this kind of loading leads to that the top of the cylinder deforms...but with the mentioned way of connekting the loadingpoint makes it stiff...

Have you tried a distributed coupling?

The magnitute of the shear traction should be set such that by integration to get the applied moment.
