Simulation of chains of manufacturing processes. Development of physically based constitutive models. The latter are coupled with models for the microstructure evolution.


The finite element method, basic course for linear, static and dynamic problems in heat conduction and analysis of deformations.
The finite element method, advanced course that extends the basic course to non-linear problems. It has is limited to simulation of forming. It can be extended with the manufacturing processes; welding, machining and powder compaction.  The focus is on the modelling issues and less on the fundamental theory.
The finite element method for nonlinear heat conduction. Self study course about the fundamental theory and vfinite element formulation of nonlinear heat conduction.
The finite element method for nonlinear deformations. The fundamental theory and finite element formulation for elasto-plastic problems with large deformations and strains.
Methods of Weighted Residuals (part in the course  Multiphysics, modelling and simulations). Fundamental theory for finite element formulations of partial differential equations.
Material mechanics. Plasticity and creep. The course is a meeting point for Engineering Materials and Continuum Mechanics. The basic deformation mechanicsms for plasticity and creep are treated together with constitutive models.
