Abstract
Importance of investigation based on mechanics of powder compaction is emphasized: this paper deals with a study of powder compaction process by simulations based on continuum mechanics approach and based on particulate modeling. Constitutive equations for powders undergoing compaction are first briefly described and examples of application of these equations to the finite element simulation of isostatic compaction and closed-die compaction are given. Foundation of simulation based on particulate modeling is then discussed and a few examples of the simulation are described. It is pointed out that both of the methods attain their drawbacks, and therefore it is necessary to employ them so that they compensate each other for investigating the behaviour of powders during compaction processes.
