Investigation of Hexagonal Honeycomb Topology for Impact Optimization in Energetic Material

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The regulation of the mechanical properties of energetic materials manufactured by traditional processes is constrained. However, the introduction of lattice structures can facilitate the regulation of mechanical properties without necessitating alterations to the materials themselves. Using finite element analysis and experimental validation,
