AB  - The quasistatic contact problem with dry friction, contributes to the achievement of a numerical model for the simultaneity of different kinds of viscoplastic, incompressible materials forming. Starting from a variational formulation of the problem, which extends the static case, a perturbed Lagrangean, discrete formulation within the framework of finite element method is obtained. On the contact boundary we have used a method based on contact finite elements, with three nodes, for the unilateral contact conditions with the friction law. One numerical example is presented.
