Mooney Rivlin for Natural Rubber

[Dhawal]

hi

I have read in many articles the kind of data used for to calculate the Mooney Rivlin constants. There are various test like,
1.Uniaxial.
2. Equi-Biaxial.
3. Planar Shear.
4. Volumetric Compression.

Unfortunately such a data is not available with my college and the rubber industries working around me. I am looking for the stiffness data, for the above test, Natural rubber with a hardness of 40 °A, 50 °A , 60 °A, 70 °A. The data which u send me will be highly important and would greatly help me in completion of my project.

Also pls tell me where i can get the data of the sterss strain i have one whis is posted here that 55pph carbon that hardness is to say 65 A i need more help

coz i need to have a comperative data of various hardness and their analysis

regards

Hello Dhawal,

You can download data for NR with 55 pph carbon black from the Materials and Methods page (http://www.polymerfem.com/modules.php?name=Materials_Models&material=8).

You should be able to find other experimental data if you do a literature search.
