EXPERIMENTAL AND NUMERICAL INVESTIGATION OF IDEALLZED CONSOLIDATION PART 1: STATIC COMPACTION

摘要

In order to investigate the compaction of homogeneous and composite powders under carefully controlled conditions, idealized two-dimensional compacts were constructed using rods of aluminum and hardened steel. Special attention was paid to the material behavior of the rods, the die boundary conditions, the periodic packing arrangement, and the shape change during ejection from the dies(springback). Corre- sponding finite element simulations of uniaxial compaction were carried out.
