The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

ABSTRAKT

Laser initiation can provide a safe and effective way to remotely destroy unexploded ordnance. In order to better understand the processes taking place and to provide a predictive capability, a comprehensive theoretical model has been formulated for simulating the physical and chemical processes associated with the laser initiation of explosives contained in a shell. The formulation is based upon various experimental observations and physical principles. Many complex processes are taking place, due to interactions of the laser beam, metal shell, and explosive core. Each of the important processes was examined in detail as a submodel; the combination of these submodels formed a complete description of laser drilling and initiation. The overall formulation considers the following major processes: 1) laser heating of the metal shell casing, 2) melt layer formation and expulsion of molten material from the heated zone due to the recoil pressure force generated from metal vaporization, 3) bubble formation and bursting in the melt layer, 4) ejection of liquid droplets from the rupturing bubbles, 5) in-depth heat transfer to the metal and solid explosives, 6) formation of a high-velocity plume jet of metal vapor, 7) turbulence interaction and chemical reaction between the plume jet and ambient air, 8) liquid- and gas-phase chemical reactions of the RDX explosive in producing fragmented chemical species, and 9) runaway ignition of RDX explosive caused by laser energy input and chemical reactions between the decomposed species of RDX. Wherever possible, experimental data have been incorporated. The model presented here provides the most detailed and complete formulation available for this topic.
