| Abstract: | Summary. This work deals with the approximation of a time dependent variational inequality modelling the unilateral contact problem
of elastic-viscoplastic bodies in a bidimensional context. The problem is approximated in the space variable with nonconforming
finite element methods which allow the handling of nonmatching meshes on the contact zone. Several error estimates are established
and the corresponding numerical experiments are achieved.
