The NIMIC organised a workshop under the tit le "Small-scale Testing and Modelling", which was held at the Four Points Hotel, Fort Walton Beach, FL, USA from the 24th to 28th January 2000. The main objective was to bring experts in the testing and modelling communities together to discuss how small-scale tests and models could be applied and developed to assist in the hazard assessment of munitions. Gaining greater confidence in the ability to understand and, as a consequence, reduce the hazard associated with munitions continues to be of considerable importance to the IM community, striving towards reducing weapon vulnerability.

Since results from appropriate small-scale testing and modelling of initiation and development of deflagration could provide additional confidence in IM assessment, the workshop goal was to improve the understanding of the mechanisms of initiation and the prediction of the response of munitions to thermomechanical threats by using small-scale testing and modelling. Appendix I indicates how the group discussions were structured.

BACKGROUND AND AIMS OF THIS REPORT

In this report, the NIMIC has published the conclusions reached by each of the four discussion groups into which the workshop attendees were divided (Appendices A-E). Those conclusions were constrained by the time available for discussion. This Conclusion section is intended to summarise the conclusions and to amplify them, where necessary, by additional NIMIC commentary. Sources of extra data include the conclusions from previous workshops, papers produced for this workshop and discussions on it held in the NIMIC, consistent with its role to analyse and add value to information. The commentary is offered as a basis for planning a way forward and concludes with several suggested topics for further study.
