Rotating a cylinder around its own axis in explicit yields very high stresses. Why?

Rotating a cylinder around its own axis in explicit yields very high stresses. Why?

(OP)
Hello

I made a very simple problem to learn explicit.

- I made a cylinder of steel.
- I coupled the whole instance to a RP lying on the axis going through the length direction of the cylinder.
- Using displacement, I rotated the RP 1 rad about the length axis. All other DOF are set to 0

Using different combinations of time and density, the lowest MAX-stresses I get are around 2000 MPa.

What am I not understanding here? I am expecting close to zero stresses when I do it quasistatically!

Thank you for your help!

Best regards

I thought I was solving this by using a smooth step?

Is there another way you may recommend?

Thank you!
