Silicone rubber

Uniaxial compressive data for silicone rubber obtained at room temperature at different applied strain histories.

Hi - is there a manufacturer or durometer value connected with the rubber represented by this test data?

Thanks.

I am afraid that I don't have that information anymore

Jorgen,

Thanks much for the three (3) sets of raw data for the silicone rubber material. It imported nicely into Excel and graphs well. Would you be so kind to elaborate on the features of the three columns of data per test? I presume that negative numbers on columns 2 and 3 indicate that the sample is under tension and that the xsection is rectangular and not square. Were these tests done with dog bone style coupons and if so is there a link or site I can go to get those dimensions. If not, that is OK as I am getting the stress~strain curve of our 10 durometer material from our supplier. It was just academic. Thanks again for all your help.

The silicone rubber data contains three columns:
col 1: time in sec
col 2: true strain
col 3: true stress in MPa

The tests were performed in uniaxial compression on cylindrical specimens. The specimen dimensions followed an ASTM standard (I don't recall which one right now). The height was about 10 mm (?), and the diameter about 25 mm (?).

Jorgen,

Prints like a charm and like some things the hard ones I figure out, the easy ones like this, I just scratch my head. A good accurate stress~strain curve to me is a thing of beauty, and sometimes hard to get. It reminds me of the phonograph needle of a record player or a lens of a good camera. No matter how powerful, accurate and extensive a system may be, it is only as good as the upfront information. So making it available is very much appreciated. ( btw - I will be generating my own curve for this material, but this one is good for verification tests )

When I get further along, I will post some of my results at the appropriate forum website for others to look at and critique. Thanks again for all the help.

Hi,
I am looking for experimental data for silicone rubber. I want to use the Mooney Rivlin Model.
The objective is to know how much energy I can store in a silicon cord under uniaxial tension.
Problem is that I need the data for tension. I would need C10, C01 and C11.
I assume the material as incompressible.

Hi,

I'm also looking for material data for Silicone Rubber. The Sample data in that zip file only goes up to 0.7 strain. Ultimate elongation would be up to 500% roughly. Is there more sample data?

[Jorgen]

I am afraid that is all the data that I can share at the moment
Let me take a look and see if I can "dig up" some for data for Silicone Rubber...
