The Numerical Simulation of the Dynamic Compaction of Powders

  • David J. Benson
Part of the High-Pressure Shock Compression of Condensed Matter book series (SHOCKWAVE)


An understanding of the dynamic compaction of powders on the micromechanical level is necessary for designing and optimizing the dynamic compaction process. The random particle packing in powders, the distribution of particle sizes, the nonlinear material response, and the large strains and vortices in the material behind the shock prevent a detailed analytical treatment on the micromechanical level. Finite element and finite difference methods provide a means of studying the interactions between the individual particles in detail during shock compression. Although the direct numerical simulation of the shock compaction of a powder remains a challenging area of research, substantial progress has been made during the last few years.
