    If you have C10 and C01 Mooney Rivlin constants as well as the modulus in psi, do you just enter these as the first and second constants in a hyper-elastic Mooney-Rivlin model or is there some further conversion required?

      If you have C10 and C01 Mooney Rivlin constants as well as the modulus in psi, do you just enter these as the first and second constants in a hyper-elastic Mooney-Rivlin model or is there some further conversion required?  I wanted to try some values I got from a table that converts Shore A hardness to modulus and C10 and C01 Mooney-Rivlin constants.  The values we used in the Sim Prem o-ring tutorial are much higher than even the 70 Shore A values in that table so I am curious if that o-ring in the tutorial is even a rubber or something far stronger like a metallic seal.  The values in the tutorial are 840 and 260 I believe, whereas the table I have suggests using C10 106.72 and C01 as 26.68 for a Shore A of 70.  Should I be able to use C10 and C01 as the first and second constants, resp. in the Mooney-Rivlin hyperelastic model in Simulation?

       

      Thanks for any advice on this.
