Hookean materil from Mooney-Rivlin

[wils]

I've seen quite a few posts and entries regarding getting Mooney-Rivlin data from experiments etc, but my problem is the opposite: I have Mooney-Rivlin data, and need E, nu (Young's Modulus and Poisson's ratio) for a given strain.

Any hints would be really helpful.

One easy way is to create a simple one element FE model with the Mooney-Rivlin model, and the calculate the stress-strain response. From the predicted data you should be able to determine what you need.

There are faster closed-form answers, but different FE programs define the Mooney-Rivlin model slightly differently making it more difficult to give a unique answer.
