Computational Methods for Thermo-Elasto-Plastic Contact

This thesis deals with the numerical treatment of contact problems considering inelastic deformation and thermomechanical coupling. For this purpose, a novel finite element approach for elasto-plasticity at finite strains is developed and two different methods of numerical contact mechanics derived: the dual mortar method with a focus on isogeometric analysis and the Nitsche method for nonlinear problems. All developed methods are investigated via both isothermal and thermomechanical problems.
