# VFRIC

 User subroutine to define frictional behavior for contact surfaces. User subroutine VFRIC: can be used to define the frictional behavior between contact pair surfaces; can be used when the classical Coulomb friction model is too restrictive and a more complex definition of shear transmission between contacting surfaces is required; must provide the entire definition of shear interaction between the contacting surfaces; can use and update solution-dependent state variables; cannot be used in conjunction with softened tangential surface behavior; and cannot be used with the general contact algorithm. The following topics are discussed:
