Construction of a True Compaction Curve: critical review of the closed die compaction test for powdered materials
Programa Editorial Universidad Autónoma de Occidente
Powder compaction keeps as a main process within the realm of powder metallurgy and the investigation towards even more accurate powder compaction engineering has achieved many goals, whilst at the same time faces many challenges. As the problem has been present from the very beginnings of powder metallurgy as a feasible manufacturing process, engineering research has arrived to the stage of mathematical modelling and computational simulation aimed at prediction of density distribution and failure occurrence within the compact. Hence the design of proper die shapes and punching routines. Yet, the success of these approaches lies on devising a proper constitutive model to a given material, as well as equations describing the evolution of internal variables characterising the extent of plastic deformation. These issues entail a careful and dependable model calibration.
