It has been known for more than fifty years that the initiation and detonation of heterogeneous explosives is affected by the behaviour of density discontinuities and other defects. Mathematical models to describe this reactive behaviour are almost as old.

A NIMIC workshop, entitled IM Design Technology, will be conducted in cooperation with the Defence Ordnance Safety Group (DOSG, UK) in September 2003, in Shrivenham, UK. The aims of the workshop will be:

The response of explosives and gun propellant beds to direct impact by shaped charge jets has been intensively studied over the past fifteen years by Germany, France, UK and US.

This paper discusses two issues that are currently of interest to the IM community: ageing and cook-off.

AC/310 SG 4 agreed that the fundamental differences in approach to IM national policies should be resolved before preparing a new edition of STANAG 4439 and tasked NIMIC to conduct an investigation of IM methodologies applied by each country for assessing the IMness of munition

The following sections of this document are dealing with the principal elements of the compression wave initiation models that have been developed over the years and implemented in hydrocodes.
This includes:

NIMIC organised a workshop entitled "Cost Benefit Analysis (CBA) for the Introduction of Insensitive Munitions into Service", which was held at Rimforsa Kursgård, Rimforsa, Sweden from 11th to 15th June 2001.

One of the stimuli specified in NATO STANAG 4439 on Insensitive Munitions (IM) requirements, and in the national IM requirements of the United States and France is fragment impact, or fragment attack.

One of the potential threats identified in NATO STANAG 4439, Policy for Introduction, Assessment and Testing for Insensitive Munitions, is Fragmenting Munition Attack, or Fragment Impact as it is more commonly known.
