| Jul 14, 2012 at 17:07 | comment | added | Yi-Ping Huang | Thanks for the link, my question is more like how to start from microscopic model which contain only conservative forces to derive the macroscopic description of the system. I am not quite sure whether this approach is possible or not. For friction, naively, I would expect some kind of two-dimensional disorder system, but I am not quite sure whether it is possible or not to think along this line...I believe it is related to statistical mechanics though...but I have no idea how to do this kind of coarse-graining. | |
