Abstract [en]

An analysis of powder processing requires accurate material models of the various powder mixes that are available. The set of material parameters for a given material model in metal powder pressing simulations is extensive. In order to model the behaviour of an Fe powder, a fitting of the parameters to experimental data has to be made. In this work, optimization methods are used to fit the parameters of material models to triaxial load test data of Fe powder. A prototype material database is developed where data describing material behaviour based on tests are separated from the material parameters of specific material models. The tools for fitting of material parameters operate on the material database. With this concept, the material parameter fitting can be performed and evaluated at the time of the analysis and can be based on e.g. the expected range in strains, temperatures or timescale. The material database is incorporated is a system with integrated product design and non-linear finite element codes
