Powder Compaction in the Axisymmetric Case

Abstract

Investigation into the interaction between oblique shock waves in porous materials and powders is a topical problem in optimization of loading conditions for obtaining, from a given sample, a compacted material with spatially uniform physical and mechanical properties. In compacting a powder in the cylindrical scheme, an irregular interaction between shock waves occurs. The compacted powder displays substantial non-uniformity in particle displacements, resulting in inhomogeneity of powder characteristics and, in some cases, even in material failure. Theoretical investigations have allowed to realize modeling of processes of a shock wave loading of powder materials. Numerical simulation of shock wave propagation and experimental assembly deformation has been performed.
