Source for Mooney-Rivlin coeffcients for silicon rubber
Tue, 2014-05-13 11:10 - asiminamech
Hi everyone,
I am trying to simulate the behavior of a silicon rubber membrane which is being compressed due to the displacement od an additional part which is bonded to it. I want to model the membrane as a Mooney-Rivlin hyperelastic model. Can therefore anyone provide me with a source giving C10 and CO1 coefficients for silicon rubber?
Any help will be appreciated,
Mina

Hi Mina, Unless you can
Hi Mina,
Unless you can find the values online you will probably have to do some material testing and determine the values yourself. You may have to do this regardless because how can you know if the silicone values you find online are correct for the silicone that you are using. Here are some resources for determining the values.

google search"hyperelasticity fit pdf" then click on the first item that comes up in the search
Look at pages 498 to 500 (as well as previous pages in chapter) in R.W. Ogden's book "Non-Linear Elastic Deformations"
Perhaps you can get some ideas from the above.
