On resolving meso-scale calculations of pore-collapse-generated hotspots in energetic crystals for consistency with atomistic models
Chukwudubem Okafor, Jacob Herrin, Catalin R. Picu +4
Meso-scale calculations of pore collapse and hotspot formation in energetic crystals provide closure models to macro-scale hydrocodes for predicting the shock sensitivity of energe…

Thermally Activated Motion of Dislocations in Fields of Obstacles: Effect of Obstacle Distribution
Zhijie Xu, Catalin Picu
The thermally activated motion of dislocations across fields of obstacles distributed at random and in a correlated manner, in separate models, is studied by means of computer simu…
