How to find force required to deform elastomeric ring/donut of material a given distance?

I would like actually like to know what durometer of say polyurethane I need to deflect/move the green inner ring about .060” with the brown outer ring stationary.  With a given force of say 20 pounds on the green ring.
Given the following configuration of parts: (see attached JPGs)

Brown steel ID of 1.125”,

Green steel OD of .750”  both about .312” thick.  Deflection about .060” of the green.

Yellow the elastomeric material, say polyurethane.
The overall thickness can be different to accommodate the end results desired.
I just am not sure if Solidworks can do this for me?
