DYNAMIC COMPACTION OF COPPER-POWDER - COMPUTATION AND EXPERIMENT

A Monte Carlo/Eulerian computational code with 10(4) zones was used to simulate in two dimensions the dynamic compaction of 100 Cu particles 15-20 mum in diameter. The computational results are in good agreement with published shock velocity-mass velocity data for porous Cu compaction. The computed shapes of the consolidated particles are also in good agreement with those obtained by shock compaction at 2 GPa. The computational method may be generalized to other materials, particle size distributions, compaction rates, and higher pressures.
