[lamia]

Hello, Dr Jorgen,

I'm working on Mooney-Rivlin model for elastomer. I'm using UMAT subroutine. But i've problem to find the material coefficient C10 and C01.
Thanks for your help.

Do you have any experimental data? If so, it is easy to determine the parameters.
If you don't have experimental data, then you might have to guess the parameters.
