abstract = {<p style="text-align: justify;">A class of steady-state metal-forming problems, with rigid-plastic, incompressible,
strain-rate dependent material model and nonlocal Coulomb&#39;s friction, is considered.
Primal, mixed and penalty variational formulations, containing variational inequalities
with nonlinear and nondifferentiable terms, are derived and studied. Existence, uniqueness
and convergence results are obtained and shortly presented. A priori finite element error
estimates are derived and an algorithm, combining the finite element and secant-modulus
methods, is utilized to solve an illustrative extrusion problem.</p>},
