Hi all,
What is the best way to model a nonlinear rotational spring? The spring should have a flexible force displacement response (moment_rotation) that can be specified.
Does anyone have some experience on that?
Thank you.

Re: Nonlinear Rotational Spring
You can use zeroLength element and assign moment-rotation relation in direction 6. Do not forget to equlDOF all other dofs.

Vesna,
The way to assign moment-rotation ralation is to play with the material in the element, right?
Thank you.

Re: Nonlinear Rotational Spring
You can define moment-rotation relationship using a uniaxial material.
