Torsion on abaqus isn't possible?
Torsion on abaqus isn't possible?
(OP)
Hello,
i try to do a torsional test on abaqus in a cylinder.
I block the lower surface and i put a rotation of 0.5rad on the upper surface, but the result isn't conform:
==> the V.M. stress are null
Can you help me please? How put a rotation on my test tube
in attachment you can find my model

Look up "Kinematic Coupling Constraints" in the ABAQUS Users Manual - there is an example there of how to apply a torsion load.

i have seen "Kinematic Coupling Constraints" it is that i want but i can't do a node set...
it's not possible to do a node set with abaqus 6-7-1 ?
with 6-9-1 it's easy but in my work place i just have the old version 6-7-1

Create the reference point, then create the coupling constraint by picking the ref point and then the surface you want to couple to. CAE will create the node set for you when you mesh the part in the Mesh module.

but when i impose a rotation on the rotation on the master node the slave surface don't rotate.
i thinks this because the V.M. stresses are nearlly null

I can't look at your CAE file I'm afraid, as I don't have access to CAE at home.
