Abstract

This thesis investigates the behavior of a metal powder in the context of the powder deposition process in powder-bed-based additive manufacturing processes. The aim of the thesis is to develop a realistic numerical model based on experimentally determined reference data for the metal powder. To this end, angle-of-rest tests are conducted using the copper alloy CuCr1Zr, and experimental data from a ring shear cell are used to parameterize the model. The experimental investigations using the cone test and the specially developed wall clearance test show well-reproducible behavior, with both tests yielding a value of approximately 26°. Based on this, the simulation model is constructed, and the attractive force between the particles is systematically varied. It is found that without an additional cohesive interaction, the angle of repose in the simulation is significantly lower than the experimental results. Only by accounting for an attractive force between the particles can a realistic approximation be achieved. The best agreement is obtained for values between 2×10¿¿ and 3×10¿¿ N. Overall, the work demonstrates that the combination of experiments and numerical simulation is a suitable approach for investigating the flow behavior of the powder.
