hp-Finite Elements for Elastoplasticity
Patrick Bammer, Lothar Banz, Miriam Schönauer +1
This article considers a model problem of elastoplasticity with linearly kinematic hardening and presents hp-finite element discretizations of two equivalent weak formulations each…

A Semismooth Newton Solver and its application to an -FE Discretization in Elastoplasticity
Patrick Bammer, Lothar Banz, Miriam Schönauer +1
In this paper, we consider a class of systems of nonlinear equations, which arise in discretized mixed formulations of problems in solid mechanics by -finite elements. We intro…

Error estimates for perturbed variational inequalities of the first kind
Lothar Banz, Miriam Schönauer, Andreas Schröder
In this paper, we derive a priori error estimates for variational inequalities of the first kind in an abstract framework. This is done by combining the first Strang Lemma and the…
