Title Plasticity at small strains with nonlinear kinematic hardening
Abstract We introduce phenomenological models for plasticity at small strains and particularly focus on the mathematical description of so-called hardening phenomena. We are interested in showing existence results for the quasi-static evolution under external forces. So far these results are either limited to linear hardening or rely on a higher gradient theory.
We present an existence result for nonlinear kinematic hardening without plastic gradients in one dimension.
