An integrated approach using simple experiments, load-displacement curve; strain on outer circumference of die; load on bottom and top of the powder pellet and strength tests for pellets, is presented. Related equations are derived which can be used to characterizes powder behavior as well as the powder-die interaction. These material parameters are used in simulations and the results of these are compared to experimental findings. The applicability of the integrated approach is tested globally and locally. For the local determination of density we employ X-ray computer tomography to directly measure the density experimentally. The restrictions of computer tomography in powder compaction applications are specified. We study simple and complex geometries of powder compacts and emphasize on the comparison of the density distribution between experiments and simulation, because the density is a mayor indicator for the quality of compressed powders and getting correct predictions by simulations is cost-saving with respect to executing a high number of experiments.
