Studienarbeit aus dem Jahr 2008 im Fachbereich Ingenieurwissenschaften - Maschinenbau, Note: 1,0, Universität Karlsruhe (TH) (Institut für Technische Mechanik, Lehrstuhl für Kontinuumsmechanik), 14 Quellen im Literaturverzeichnis, Sprache: Deutsch, Abstract: The Thesis considers the implementation of metal-plasticity for computer simulations.This is done by an Backward-Euler-Algorithm, which is a stable way of time integration for nonlinear differential equations. On the one hand the classical appoach of consistent linearisation at the example of a nonlinear isotropic and kinematic hardening von-Mises-Model. On the other a variational approach is used to implement the single crystal plasticity of the lattice type ffc. Both are given in rate dependend and geometric linear context. The text includes a short introducion to the topic and the used mathematial tools, detailed calculations of all equations used for the plasticity model and various simulated examples.
