Abstract
This study describes a model for initiating an explosive decomposition of composite materials based on high explosives that weakly absorb radiation and ultrafine metal inclusions under the influence of nanosecond laser pulses. The model is based on experimental data obtained by investigating the explosive decomposition of PETN with ultrafine metal particle inclusions (Al, Ni, and Fe). The model serves as a basis for constructing a scientifically grounded algorithm for determining the composition of a material with minimal thresholds for laser initiation of explosive decomposition, which makes it possible to replace most experiments with theoretical calculations and optoacoustic measurements. The algorithm is verified using data from laser initiation of RDX with inclusions of ultrafine iron particles.
期刊介绍：
Combustion, Explosion, and Shock Waves a peer reviewed journal published in collaboration with the Siberian Branch of the Russian Academy of Sciences. The journal presents top-level studies in the physics and chemistry of combustion and detonation processes, structural and chemical transformation of matter in shock and detonation waves, and related phenomena. Each issue contains valuable information on initiation of detonation in condensed and gaseous phases, environmental consequences of combustion and explosion, engine and power unit combustion, production of new materials by shock and detonation waves, explosion welding, explosive compaction of powders, dynamic responses of materials and constructions, and hypervelocity impact.
