In this paper we introduce a phenomenological friction law for the continuous sliding of a polymer on a surface of aluminum for lubricated and dry conditions as it occurs in metal forming processes. The contact model is developed within the framework of continuum thermodynamics of irreversible processes with internal variables and for large strains assuming the contact area as a material surface. The model reproduces the boundary friction map resulting from the experiments carried out in Luengo et al.(2000).
