Construction of a true compaction curve: critical review of the closed die compaction test for powdered materials
Autor: | Mauricio Barrera, Helver |
This job came of an investigation about a new model called Energy Split Hypothesis (onwards ESH), which is proposed and experimentally tested for the closed die compaction test based on a statement of energy conservation. It was motivated by the observed
data scattering in constructing the compaction curve, making use of the well-known Method of Differential Slices (onwards MDS). As part of this was addressed the problem of uniform fill-density before compaction, when using specimens of different size. As with testing the validity of the ESH, the methodology is based on a statistical analysis of the observed data scattering upon experiment repetition.
