abstract = {<p style="text-align: justify;">We study the dual mixed finite element approximation of unilateral
contact problems. Based on the dual mixed variational formulation with three
unknowns (stress, displacement and the displacement on the contact boundary), the a priori error estimates have been established for both conforming
and nonconforming finite element approximations. A Uzawa type iterative algorithm is developed to solve the resulting linear system. Numerical example
shows good performance of the method.</p>},
