Hydrostatic Creep Data for Rubber
- Thread starter dcopps
- Start date
"Elastomer creep data" into Google brought up a lot of links.
"Rubber" is a bit of a loose term, I guess.
For plastics it's usually "isochronous stress/strain" data - although the availability is very patchy and limited to few manufacturers.

It's ok to soar like an eagle, but weasels don't get sucked into jet engines.

I don't think that rubber will creep under purely hydrostatic pressure.

I don't think any material will creep under hydrostatic pressure, unless it has a lot of voids or other discontinuities that generate shear stresses. Pure hydrostatic pressure generates no shear stresses.
What do you want to do with the data?
You will most likely need to run the test yourself or have a test lab run it for you. Rubber materials vary, sometimes dramatically.
I agree with the previous posts that unless there are voids in your material, I doubt you will see much.
In my previous job we would run a hydrodynamic test (volumetric test) to obtain data for material modeling for FEA in place of assuming a poisson's ratio.
Good luck.
