Pre-tension a flexible elastomer disc

Hi All,

I have a disc made of soft flexible material that needs to be stretched over a tube opening.
Is it possible to apply a pre-tension load across the surface to simulate this?
The geometry I modeled should be the correct shape under tension.

I could define a cylindrical coordinate system and apply a radial displacement to the outer edge,
stretching the surface. Instead I'm trying to do the opposite; keep both edges in place and
assume the surface has an internal tension already applied.

(I'm thinking something like the bolt pretension condition but acting radially on the disc)
