Jan Stránský proposed the following answer:
Hi Behzad,

I think that you will need new Material, IPhys, Ip2 and Law classes. Have a
look at FrictPhys related classes for an inspiration (see one of previous
answers). Try to understand the relations between those classes. If
everything is clear to you, the extansion to Burger's model should not be a
big deal :-)
cheers
