Use of jump-tests for the characterization of the viscoplastic behavior of pharmaceutical powders during compaction

The present work details viscoplasticity, especially by choosing products that are known to present little viscoelasticity. Full paper available in the PAPERS section.

Stress transmission coefficient is a reliable and robust parameter for quantifying powder plasticity

New paper featuring studies by the University of Minnesota.

Head to the papers section and discover that

- STC (Stress transmission coefficient) affects transmission of stress to die wall
- STC correlates well with the plasticity of a large set of powders
- STC is free from errors in traditional methods for quantifying pasticity
