Finite Element Analysis of Nonsmooth Frictional Contact
A nonsmooth contact class of algorithms were introduced by Kane et al.  and extended to the case of friction by Pandolfi et. al . The formulation specifically addresses geometries for which neither normals nor gap functions can be properly defined, e.g. bodies with corners. The formulation provides the incremental displacements in variational form, following from a minimum principle. Selected numerical examples of application of the algorithm are presented here.
