Stress and Density Distributions in the Compaction of Powders
Stress-strain curves for a compacting powder were obtained from tests in a specially developed high-pressure triaxial apparatus. A powder-wall shear apparatus was used to determine the stresses at a wall as a function of the powder-wall displacement. Calculations of stress and density distributions in a “two-dimensional powder compact” were based on mathematical relationships for the stress-strain response and for the powder-wall interaction. The results of these preliminary calculations show promising agreement with known experimental data.
