Torque in ABAQUS
Hi,
I've got the same problem. I don't know how to apply a torque in Abaqus. Somebody can help us????
Thanks,
Coupling to a reference node
Guys, your best bet is to use a kinematic constraint. I had a similar problem, but in my case I wanted to apply a rotation to a surface of nodes that only had 3 degrees of freedom (displacements only). This was effected by the inclusion of the following lines in my .inp file:
** Constraint: Constraint-1
*Coupling, constraint name=Constraint-1, ref node=_PickedSet14, surface=_PickedSurf13
*Kinematic
You then can apply the concentrated torque to the reference node. In my case, I applied a rotation to the reference node. It is only fair to say that I had to get some support from ABAQUS/Simulia support and generated everything initially in ABAQUS CAE.
