Included in this analysis are an anisotropic property of powder grains and heat conduction between hBN and copper particles. Results confirm the earlier observations that the effects of copper are to increase shock pressure and to act as a heat sink to cool BN grains. But, the simulation also reveals that the shock processing at the particle level is far more complex than those suggested in the literature and that the interpretation of process parameters based on macroscopic conditions requires caution.}, number={1-3}, journal={JOURNAL OF MATERIALS PROCESSING TECHNOLOGY}, author={Horie, Y and Yano, K}, year={1999}, month={Jan}, pages={109–114} }

The average diameter of model grains was 12 \ensuremath{\mu}m. Results show highly transient vortical flow fields and strong particle velocity dispersion that are consistent with the experimental results of Mescheryakov and his associates. Characteristic times for these phenomena were on the order of acoustic propagation times across the grains. The number of vortices increased with shock strength, but their size decreased almost inversely. Ejection of copper particles from the back free surface of the specimen was also observed. The cause of ejection is grain boundary cracking.}, number={21}, journal={PHYSICAL REVIEW B}, author={Yano, K and Horie, Y}, year={1999}, month={Jun}, pages={13672–13680} }

Results show (i) a trend-wise agreement between the two models, (ii) nonequilibrium distributions of particle velocity dispersion, and (iii) particle velocity dispersions of 20–100 m/s for a 10 GPa shock wave in Ni/Al mixtures and 5–70 m/s for a 5 GPa shock wave in Ti/Teflon mixtures. Particle velocity dispersions of this magnitude are thought to be the driving mechanism for initiation of chemical reactions in reactive solid mixtures.}, number={3}, journal={JOURNAL OF APPLIED PHYSICS}, author={Yano, K and Horie, Y}, year={1998}, month={Aug}, pages={1292–1298} }

The condition is based on a concept of energy balance whereby a sudden increase in interface areas is equated to fluctuating local kinetic energy.
