%T On variational updates for non-associative kinematic hardening of Armstrong-Frederick-type
%U 
1-3 
%X simple fully isotropic plasticity models, their extensions to more realistic constitutive laws, particularly to those showing non-associative evolution equations, is highly challenging. In the present paper, a class of finite strain plasticity models characterized by nonlinear kinematic hardening resulting from non-associative evolution equations is recast into an equivalent minimization principle yielding a variational constitutive update. As an important prototype, a variationally consistent Armstrong-Frederick model is discussed.
