Simulation of Die-compaction Process for Multi-stepped Part

Abstract

Simulation of powder compaction in closed die is carried out by the elastic-plastic FEM. The study is focused to investigate the effect of toll kinematics in die-compaction on density variation in a multi-stepped part. Based on the simulation results, it is shown that there is an appropriate tool kinematics that provides a small variation in density in the obtained compact. It is also shown by the simulation that a slip crack-like defect can occur depending on the tool kinematics.
