Chareyre proposed the following answer:
Hi,
The parameters in Material classes cannot be "studied" because they are
only numbers with names, not well defined physical parameters (suprising
maybe).
Better start thinking the other way around: look what kind of contact
parameters the law functors are using, then how this contact parameters
are defined based on material parameters.
You will see that different functors lead to different interpretations
of what Material::poisson is.
For Ip2_FrictMat_FrictMat_FrictPhys+ Law2_ScGeom_FrictPhys_CundallStrack
the normal force is independent of Poisson, yes. It is the expected
behavior.
I hope it helps.
Bruno
