Question

Mechanica: axial torque in 2D Axisymmetric?

Can I model a shaft with an applied torque along its axis in 2D Axisymmetric?

From the help:

"You can define loads, constraints, and other model attributes in three degrees of freedom for a 2D axisymmetric model:

  • translation in X and Y (or the cylindrical and spherical equivalents)

  • rotation in Z (or the cylindrical and spherical equivalent)"

where the model is created in the XY plane, and revolved about the X=0 line (i.e., the Y axis)

so it looks like the answer is "no" as I'd want either a moment in Y, or a (tangential) force in Z.

Any pointers? It seems 2D Axisymmetric is very limited if it can't model shafts!

Hi John,

You are correct, the answer is no. You can not apply a torque about the axis of a 2D axiysmmetric model.
