Rotational Moments on Deformable Bodies

[abaqus1234]

Hi, I am trying to build a simulation, where a rotational moment is applied on a deformable body. The way that I have defined the rotational moment doesn't seem to be causing any rotation, and I was hoping someone could help me validate my steps:

1. I created a deformable body.
2. I created a RP on the body and assigned a kinematic coupling constraint of the entire deformable body to that RP.
3. I assigned a CM1 rotational moment to the RP.

Is there a step that I am missing here?

Thanks!

Don't assign it to the whole body, use a surface instead. Check some tutorial videos showing torsion analyses in Abaqus. You could also use rigid body constraint for this purpose.

Thank you! Can I still use a rigid body constraint for a deformable object?

 

[FEA way]

Yes, it will affect only the surface to which it’s applied. That’s the most common way of simulating torsion in Abaqus.

Thanks SO much!!
