Abstract Scope |
Detonation of solid explosives is facilitated by the presence of microstructural features and defects that result in local temperature increases when impacted by thermal or mechanical insults. These local temperature spikes are known as hot spots and can trigger chemical reactions that may lead to a detonation. Therefore, understanding the evolution and variability of microstructure and defects during processing and various environmental conditions is of extreme importance to develop models that can predict the performance of explosives. We present phase field simulations that predict the microstructural evolution during synthesis by vapor deposition of explosive thin films. Specifically, we couple thermo-mechanical stresses to study synthesis and aging of thin films under varying thermal conditions.
