How to apply torque to solid body

LZanell

Hi,

I'm trying to figure out how to apply a moment of force to a face of a solid body. Specifically, I want to apply a torque to a cylindrical face (or any face) of the body, but I'm having difficulty because the part related to the moment application is not usable when I select the face (I cannot insert a value).

What I've though is to create a RBE node ad to apply the torque at the node but guess is not the correct way due the fact that I haven't only a tangential force into the cylinder but I've also a radial force due to the RBE connection that gave me a wrong output in terms of radial force (that is not expected).

How can I do this in order to have a moment (and only a superficial moment) applied to a face?

thanks

Hi Ludovico,

The 2nd approach is the correct way to apply moment to solid elements.

See the attached image.

Hi Rajashri,

considering that I'm appling a torque inside a pipe without deforming the diameters (due to the fact that I'm trying to model the torque given by another pipe with interference inside the main pipe and is not supposed to have diameter deviation) could be a better option to apply a RBE2 node?

Thanks

you can try with RBE3.
