Laser-induced Micro-explosion: A Micro-zone Explosive Simulator for the Characterization of Explosives

Abstract

The determination of detonation performance and sensitivity is an important research content of explosive testing technology. However, the traditional test method usually requires a large amount of samples due to the limitation of the critical diameter and other detonation conditions. Therefore, it will inevitably bring great test risk, high test cost and measurement uncertainty. In this case, it is urgent to develop new testing technology with small dosage and high precision. Recently, a micro-zone explosive simulator for the characterization of explosives is proposed by Wang and Liu et.al. According to their work, laserinduced micro-explosion is produced by micrograms of explosives irritated by pulsed laser, has been proved to be closely related to macroscopic detonation. Therefore, it can be used as a micro-zone explosive simulator for the characterization of explosives. The aim of this letter is to shed new light on the determination of detonation performance and sensitivity and highlighted the importance of close integration of experimental, statistical, and theoretical efforts.
