Confined high-load compression of particle beds
Contact person: Konstantinos Giannis
“Confined high-load compression of particle beds” is being applied in a wide range of fields, among others are powder metallurgy and pharmaceutical industry. In most of these applications, variables such as anisotropic characteristics of compacts regarding their mechanical strength, porosity, internal surface areas and others play important roles in the formation of a compact.
Although high-load compaction has been around for a while, there is a need for better understanding of the mechanistic principles that give birth to the different aspects of intra-compact inhomogeneities, which may very well be rooted during the evolution of events taking place during powder compression. The aim of this project is to investigate these phenomena and their evolution.
We will attempt to establish a Distinct Element Method (DEM) formulation which will allow us to numerically reproduce both macroscopic characteristics of a compact as well as its internal micro-structure which can then be effectively studied.”
