Abstract
Isostatic compaction of a porous billet in an incompressible container is considered. The behavior of the container as well as the matrix phase of a porous billet is assumed to be described by power law equations. Macroscopic deformation of a billet is controlled by flow theory for a compressible body with a smooth potential. It is established that the stressed state in a billet is not isostatic.
