May I suggest you take only a slice of the wheel, use a rotational displacement of a planar face (such as the wheel and not the tire), and prescribe the displacement to be no more than 30 degrees? You will also need an axis so that you can prescribe and measure more easily.
I'd also recommend beginning with this problem as a 2D plane strain problem.
As for your characterization of the material, if you expect very large displacements under minimal loads than you're best off using a hyperelastic material model. However, you will need three input curves (stress-stretch).
One particular challenge I see you needing to overcome is the applied load (1470N) remaining on the hub.
Is the tire not pre-stressed on to the wheel?
Hi Chris and Adam,
Thank you for respond.
I tried a different variations of static non linear setup, even start with 2D plane in the begging, but left that idea when i realized that i have narrowed options regarding constraints.
Secondly, i don't know how to set up rotational displacement. I understand that you meant to set some kind rotation to the wheel around the axis for an angle, but fail in doing this. I don't know how to set it up. I've gone thru all fixture options and read all help.
Tire does not have influence on the wheel. They together are "bonded" and their rough weight on the path is 1470N. And I was expecting small deformations out of the tire, not large. I think that i will not engage in pursuing information for hyper elastic SBR material since this kind of simulation is hardly possible without heavy tuning.
I assume you are doing this as a dynamic analysis?
A static analysis is by definition static--nothing moves and all forces balance to zero. You can't get where you want to go (If I understand correctly) the way you are doing it.
You can create a rotational displacement by going to Fixtures, Advanced, On Cylindrical faces, and then pick the rotational button.
