Surface-to-surface contact with finite sliding.

Problem description

This section deals with finite-sliding surface-to-surface contact involving stress/displacement elements. The tests utilize different surface behavior and surface interactions with the surface-to-surface approach for modeling finite-sliding contact. The tests also illustrate examples in which different facet types are involved for master and slave surfaces.

Results and discussion

These results illustrate the accuracy and the robustness of the surface-to-surface formulation for finite-sliding contact.
