Accidental initiation of munitions via the heating of bridgewires by radiofrequency (RF) radiation (i.e. HERO) is well understood; far less work has been undertaken to determine how bulk energetic materials (cased or uncased) directly respond to exposure to RF radiation.
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.

A probabilistic analytic model of initiation for the STANAG 4496 Insensitive Munitions (IM) Fragment Impact (FI) test was developed. The deterministic Jacobs-Roslund (JR) detonation initiation model was augmented to include impact point offset and fragment tilt against a curved munition case.

During the 2018 MSIAC Improved Explosives and Munitions Risk Management (IEMRM) workshop, it was recognized by the community that low violence reaction types such as a burn on one side, and high violence reactions such as detonations on the other side, are relatively well understood.

An increasing number of munitions now show less violent responses than detonation in cook off or impact scenarios. The detonation of a warhead typically leads to well reproducible fragmentation effects.

Rocket motors are designed to propel payloads to their final destination by ejecting hot gases through a nozzle. The gases are produced by combustion of fuel and oxidizers, which can be separated (hybrid combustion) or mixed with each other (gun propellant, propellant grain).
