Thanks for the advertissement Jf ! This law is indeed maybe similar as 
the one you need. The attached figure plots the evolution of the normal 
force with respect to the interpenetration, for a contact between two 
spheres.
It is indeed controled by the save, in the physics of the interaction, 
of the maximum value of the interpenetration : unMax.
I'm just trying to write a script which could illustrate this law and I 
think I'll use for that your mindlin_test.py... ;-)

So, feel completely free to ask !
