Additive manufacturing (also referred to as AM) offers many opportunities in the munition design space to tailor bulk properties, such as spatially-variant composition, density, etc., with intent to subsequently affect macro behavior through changes in stress/strain profiles, variable
The ageing of materials in munitions as reported in the open literature is reviewed within the framework of materials engineering. The focus is on polymeric materials and molecular solids encountered in energetic materials.
Defects in energetic materials or in other materials used in munitions systems are often a cause for concern. This includes voids, cracks, and foreign materials, as well as chemical, physical and or mechanical properties that are outside design tolerance specifications.
When dealing with energetic materials, TNT Equivalency is commonly used for different purposes. For scientific purposes, it is a means to compare the explosive effects delivered by different energetic compositions, by expressing them in terms of an equivalent TNT detonation.
This report documents MSIAC’s generation of a consolidated guide to energetic material parameters needed for typical IM modeling and simulation efforts. An explanation of tests and experiments to determine the parameters will also be included.
