Abstract
Compression adiabats for alumina-based nanopowders are obtained experimentally, various conditions of pulsed magnetic cylindrically symmetric radial compaction of the nanopowders are tested, and the density distribution in the compacted powders are measured. Using the compression adiabats obtained, quasi-static compaction of a granulated (porous) medium, which is considered to be compact, is simulated. The conditions of uniform and equilibrium compaction on a rigid rod are analyzed. The voidage distribution, stress tensor, and amount of accumulated deformation are calculated. The features of nanopowder compaction, specifically, the presence (absence) of voidage nonuniform radial distribution, are explained.
