| Abstract: | A model for dynamic compaction of granular medium is proposed for the case in which the external action far exceeds the yield
strength of the material. A radial axisymmetric compaction problem is solved for a granular medium with nanosize structure
in the presence of a rigid rod at the symmetry axis. Simulated data are compared with experimental data on magnetic pulsed
compaction of oxide nanopowders.
