Abstract

Abstract

A class of quasi-steady metalforming problems, with incompressible, rigidplastic, strain-rate dependent, isotropic and kinematic hardening material model and with nonlocal contact and Coulomb’s friction boundary conditions was considered. A coupled variational formulation was derived and by proving the convergence of a variable stiffness parameters method with time retardation, existence and uniqueness results were obtained.
- quasi-steady,
- rigid-plastic,
- combined hardening,
- nonlocal friction,
- variational-analysis
