On an optimal AFEM for elastoplasticity
Miriam Schönauer, Andreas Schröder
In this paper, optimal convergence for an adaptive finite element algorithm for elastoplasticity is considered. To this end, the proposed adaptive algorithm is established within t…

A Posteriori Error Estimates for -FE Discretizations in Elastoplasticity
Patrick Bammer, Lothar Banz, Andreas Schröder
In this paper, a reliable a posteriori error estimator for a model problem of elastoplasticity with linear kinematic hardening is derived, which satisfies some (local) efficiency e…

Mixed Finite Elements of Higher-Order in Elastoplasticity
Patrick Bammer, Lothar Banz, Andreas Schröder
In this paper a higher-order mixed finite element method for elastoplasticity with linear kinematic hardening is analyzed. Thereby, the non-differentiability of the involved plasti…
