Abstract
A class of quasi-steady metal-forming problems under nonlocal contact and Coulomb’s friction boundary conditions is considered with an incompressible, rigidplastic, strain-rate dependent, isotropic, and kinematic hardening material model. A coupled variational formulation is derived, the convergence of a variable stiffness parameter method with time retardation is proved, and the existence and uniqueness results are obtained.
