The influence of pore shape on the porosity-pressure behavior of powders undergoing compaction is studied theoretically and numerically. Idealized two-dimensional models are used to compare the compression of circular pores, representing elevated temperature compaction, with cusp-shaped pores typically associated with cold compaction. An attempt is made to correlate porosity-pressure response with a logarithmic relation proven useful in the characterization of experimental compactions. A preliminary investigation on the effects of introducing a macroscopic shear into the compaction process is conducted.
