The ContactMaterial2D nDMaterial defines the constitutive behavior of a frictional interface between two bodies in contact. The interface defined by this material object allows for sticking, frictional slip, and separation between the two bodies in a two-dimensional analysis. A regularized Coulomb frictional law is assumed. Information on the theory behind this material can be found in, e.g. Wriggers (2002).
NOTE:
- The ContactMaterial2D nDMaterial has been written to work with the SimpleContact2D and BeamContact2D element objects.
- There are no valid recorder queries for this material other than those which are listed with those elements.
EXAMPLE: ContactMaterial2D nDmaterial with tag 1

Code Developed by: Kathryn Petek, Pedro Arduino, & Peter Mackenzie-Helnwein, at the University of Washington
