analisi torsionale con ansys

[peter82]

Hey, guys!
I press that I have no great experience in ansys.
I have to do a torsion analysis of a mechanical part, solid drawn in proes, subject to bending and twist.
I don't find any solid element with 6dof, how can I do it? Do I have to use shell elements?
Thank you, please, it's urgent enough... .

I am totally "ignorant" of ansys but I can tell you that in nastran when importing the solid through proe you use the main surface and discusses with shells. then to these is a thick attribute.

the knots of solids do not have 6 degrees of freedom but three. both in ansys and in nastran.
If you have to apply a solid moment you have to do it by applying a couple of forces.

 

[stefano.garbin]

correct. the knots of solid elements have 3 degrees of freedom.
to apply a moment in ansys "classic" you have to add a superficial mesh to the surface where you have to apply the moment with surf elements154.
if you use ansys workbench this step is executed automatically, just appplicate the moment.
