Abstract [en]

The global behaviour of the cold pressing process of iron powder is dependent on the process kinematics, material response in the powder as well as the friction effects in the contact between the powder and the tool walls. The analysis of powder pressing requires accurate material models of the various powder mixes that are used. The modelling is dependent on tri-axial compression tests for the material model and friction tests for the nonlinear friction model. The modelling parameters have been determined in international cooperation within the COST 512 and MMPF (Modelling of Metal Powder Forming) research programs. Component pressing with varying kinematic conditions have been performed by the Sintertech company. In this work, a set of process and model parameters have been established for numerical simulations of powder pressing process.
