L-264 Effects of Electromagnetic Radiation on Munitions Part 2: X-Ray, Gamma and Neutron Radiation
November 2020
This document is to serve as a background resource for the array of interactions that X-ray, gamma and neutron radiation may have with a munition system during the course of a non-destructive examination. The discussion of X-rays and gamma rays (energetic photons) is li

L-261 TNT Exudation, Crystal Growth and Ageing
August 2020
For trinitrotoluene (TNT) and explosive formulations containing TNT (e.g. Composition B), TNT exudation in projectiles, bombs, and rockets has been a recurring problem since the early 1920s.

L-262 TNT Equivalency of Energetic Materials: Review and Best Practices
July 2020
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.

L-250 Defect Detection And Characterization Capability Study For Energetic Materials
May 2020
Defects in energetic materials or munitions can alter their safety and performance characteristics, potentially leading to failure and causing serious damage to military equipment and injury to service personnel and the public.

L-256 A Taxonomy For The Classification Of Defects In Energetic Materials
April 2020
Following many discussions and multiple iterations over two years, MSIAC has produced a largely self-consistent taxonomy and lexicon of terms related to defects in energetic materials and munition systems, based on the paradigm of materials science and engineering.

L-257 Life Cycle Cost Method And Examples For Munition Health Monitoring
March 2020
Within the NATO context, a cost benefit analysis (CBA) is a valuable support tool for economic analysis for defence programs. A major part of any CBA is a sound life cycle cost analysis of all options.

L-218 Material Selection And Property-Processing Implications In Additive Manufactured Materials For Munitions
February 2020
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

O-214 MSIAC Workshop 2020 Defects - Causes, Classification and Criticality
October 2019
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.

L-217 Ageing Of Munition Materials
October 2019
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.

O-206 TNT and Blast Equivalency Characterization of Energetic Materials
July 2019
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.
