TORSION ON SHELL ELEMENT

[engrookie89]

Hi I am trying to apply torsion to a shell element to achieve a large revolution (around 180-360 degrees) but there isn't an option for torsion under the load module. The closest thing is a moment force.

Are there other ways of applying torsion or achieving a certain angle of twist on the shell element?

I have read on other threads you can impose an angle of twist to one end, does anyone know how?

(What I am trying to model is a long strip of inextensible material buckling under torsion, I have used a shell element because of the small thickness of the strip compared to its other dimensions)

You could assign rotation as a boundary condition. Have a look at Model>Steps>Your Load Step>BCs>Displacement/Rotation

Hope it helps.

Hi, thank you for your reply!

I also read in other forums that "kinetic coupling constraint" may also be related to torsion, I am unsure what this is, can you further explain to me

kind regards
