A Simple Geometrical Model for Solid Friction
We present a simple model for the friction of two solid bodies moving against
each other. In a self consistent way we can obtain the dependence of the
macroscopic friction force as a function of the driving velocity, the normal
force and the ruggedness of the surfaces in contact. Our results are discussed
in the context of friction laws used in earthquake models.Comment: 9 pages, plain TeX, preprint HLRZ 24/9
