Hello
I have a question about "Mooney-Rivlin von Mises Fibers" model. There is a parameter in the model called "lam_max". I was not able to figure out what exactly this parameter does. I read the FEBio help section 4.1.2.13 when it says:
The question is: How can I know what value I should use for this parameter? For example if I use <lam_max>1</lam_max> the results is very different compared to when <lam_max>10</lam_max>. For example for a hemisphere under internal pressure:

The feb file is attached. Thanks in advance for your help.

"lam_max (λm) is the stretch at which the fibers are straightened"
. This definition is not clear to me.The question is: How can I know what value I should use for this parameter? For example if I use <lam_max>1</lam_max> the results is very different compared to when <lam_max>10</lam_max>. For example for a hemisphere under internal pressure:
