This frictional contact law implements simple Coulomb friction law where [math]\displaystyle{ S_{slide} = \mu_d N \quad{\rm if}\quad S_{stick}\gt \mu_s N }[/math] and µ d and µ s are the dynamic and static coefficients of friction. In other words, the sliding will begin when it overcomes the static frictional force, but thereafter will slide …
