Numerical Simulation on Pharmaceutical Powder Compaction
In this paper, we present a modified density-dependent Drucker-Prager Cap (DPC) model with a nonlinear elasticity law developed to describe the compaction behavior of pharmaceutical powders. The model is implemented in ABAQUS with a user subroutine. Using microcrystalline cellulose (MCC) Avicel PH101 as an example, the modified DPC model is calibrated and used for finite element simulations of ...
متن کاملCompaction of Commercially Pure Titanium Powder by Friction Powder Compaction Process
A new friction powder compaction (FPC) process is introduced for compacting commercially pure titanium powder. The FPC process is very simple and energy-efficient since it requires only a rotating tool plunged into an aluminum plate with a hole filled with titanium powder, and no external heat source is necessary. The sintering of the powder is mainly achieved by the friction heat and pressing ...
متن کاملConstitutive Equation for Powder Compaction Incorporating Powder Charecteristics
The increasing importance of powdered materials fabrication has led to an increasing emphasis on the understanding of the powder behavior during compaction. During compaction, a powder mass undergoes densification owing to various mechanisms, i.e. sliding, rotation, deformation and/or fracturing of the constituent particles. These densification mechanisms are very dependent upon the powder char...
متن کاملA Crystal Plasticity View of Powder Compaction
The cold compaction of an aggregate of powder is treated from the viewpoint of crystal plasticity theory. The contacts between particles are treated as compaction planes which yield under both normal and shear straining. The hardening of each plane represents both geometric and material hardening at the contacts between particles; the macroscopic tangent stiffness can be written in terms of the...
متن کاملCompaction dynamics of a magnetized powder.
We have investigated experimentally the influence of a magnetic interaction between the grains on the compaction dynamics of a granular pile submitted to a series of taps. The granular material used to perform this study is a mixture of metallic and glass grains. The packing is immersed in homogeneous external magnetic field. The magnetic field induces an interaction between the metallic grains...
