Rigid body rotation ?

Rigid body rotation ?

Rigid body rotation ?

(OP)
Hello everyone,

I am using Abaqus for an easy compressive test. However, when I check the result, a rigid body rotation appears. I tried to block rotation 4,5,6 of my nodes to avoid this rotation, but these dofs are not active.

Is there a simple way to block a solid body rotation ?
Thank you for your help!

Post a picture of your model with your boundary conditions and loads.

RE: Rigid body rotation ?

Solid elements do not have rotational degrees of freedom so you need to constrain the transnational degrees of freedom to prevent all 6 rigid body motions.  I hope this helps.
