Abaqus: torsion in a circular tube
Abaqus: torsion in a circular tube
(OP)
Hello! One more question :) My model in abaqus is a circular tube and I need to apply torsion in one side of it. The other side is not movable, but the torsion should affect the whole segment. I apply rotation in one side but I do not good results. Do you know any other way to apply torsion? Thank you!

I had the same problem the last year when i was designing a formula student car steering system... I was new doing FEM analysis and if i see the results, maybe i would be ashamed!!! hahahaha.
Now i am more experienced and i would approach the problem as follows:
Put the boundary conditions in the unmovable side, make a set with the nodes and select U1,U2,U3.
To simulate the torsion, instead of creating a momentum in the face, create a distributing coupling to put the momentum in a node.
Master node: A point created in the middle of the cylinder face.
Slave nodes: The nodes of the face.
When you select the distributing coupling, could be enough to active only the spin that affects to the momentum. Do some tests.
Now that i have time i will try your model. Give me some dimensions and a load and i will try.
Regards.

I don´t like it.... I´m going to try different analyisis. If i achieve something i will tell you.

When you create the distributing coupling, create a surface, not a node set, and link the master node with the surface.
