Beam bending around a rigid analytical cylinder
Beam bending around a rigid analytical cylinder
(OP)
Hello,
I am rather new to ABAQUS CAE and I have been trying to resolve this problem for the past two weeks (asked every one I know but not many people have working knowledge on ABAQUS).
I have a deformable beam of an isotopic elastic material that I am trying to bend into a circular shape (with two ends of the beam touching each other). I put a boundary conditions on the beam: fixed centre, surface contact with the cylinder (it prompts the beam to bend around it) and pull forces on ends of the beam.
So far I managed to make it bend around the cylinder and start to pull together but when I add a third step (where I instruct surface contact to be initiated between the two ends of the beam) to make the beam finish it's path around the cylinder, the job produces errors.



In the end I need to make my beam twist into the following shape (see below) and so far I am nowhere near close to that.
