Challenges in Understanding the Dynamic Behavior of Heterogeneous Materials

Fig. 10 Impact-induced reactivity threshold plot, demonstrating the threshold energy (for go/nogo chemical reactions) for Ti+B+Al mixtures. The %TMD of the mixtures was kept constant,
and the Al content was systematically varied maintaining a 1:2 molar ratio of Ti:B. The plot
demonstrates an optimal stoichiometry for reduced threshold for reactivity
Fig. 11 Half-view of the rod-on-anvil impact simulations at 200 m/s impact velocity. The
temperature distribution shows that the majority of the heat localizes in bands coincident with
the agglomerated boron. This is in stark contrast with the fully dense structure simulations where
the majority of the heating was at the interface between the copper and powder
