Summary The compaction process of iron powder is considered. Due to negligible elastic strains the rigid-plastic model is applied. A yield condition containing the first stress invariant is used. All material functions depend on the relative density of the powder, which changes during the compaction process. Siebel friction law is applied, and the friction factor is considered to be depending on the relative density. Various material functions are applied in the numerical simulation, and the results are compared with experimentally obtained data. The best fitting material functions and friction factors are obtained.
