How to determine law's parameters in Abaqus ?
 
Hello,

I am working on a project concerning elastomer and his hysteretic behaviour. I have done some tests in order to determine the material parameters based on experiments. Now i would like to know how based on my graphes, i can find in Abaqus the more accurate law to describe the behavior of the material ? I mean how to implement my experimental graphes in Abaqus to find the law which describes the best that behavior.

I spent a lot of time searching some thesis and doing some tutorials but to be honest, I haven't found yet something that can be really useful to resolve my problem.
If you want any further informations just feel free in case it might not be clear to everyone. I am looking for advices too.

Thanks in advance for your answers.:)

King regards,
Jeje

This process is called "Curve Fitting".

Hi,
Thanks @karachun for the quick response, that's what i am looking for (''Curve Fitting'').
I am wondering is it just by creep tests than one can determine the hysteresis parameters ?
