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:
