Abstract
In this thesis a new displacement based formulation is developed for
elasto-plastic deformations in steady state problems. In this formulation the displacements are the primary variables, which is in contrast to the more common formulations in terms of the velocities as the primary variables. In a steady state process, a transient calculation is not required and only space discretizations are needed, without time discretizations. The evolution of the material variables is expressed as an integration along the streamlines. The resulting differential equation describes steady convection with source terms.
