Hydrostatic Creep Data for Rubber

Hydrostatic Creep Data for Rubber

Hydrostatic Creep Data for Rubber

(OP)
I am striking out on a search for my subject here. NASA's Maptis, MatWeb, Google Scholar, and the ASM handbooks, among other places I've checked, have not zeroed in on this. Any ideas? Thanks.

RE: Hydrostatic Creep Data for Rubber

"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.

RE: Hydrostatic Creep Data for Rubber

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

RE: Hydrostatic Creep Data for Rubber

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.

RE: Hydrostatic Creep Data for Rubber

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.
