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

SINOPSIS

Experimental and analytical results describing the combustion response of a porous pyrotechnic powder under dynamic loading conditions are described. Pyrotechnic powder samples were subjected to dynamic loading using a piston driven porous bed configuration. Piston impact velocities ranged from about 80 to 300 m/sec. The initial loading density of the porous bed ranged from 54 to 56 percent of theoretical maximum density (TMD). The porous bed of pyrotechnic material ignited and burned at all but the lowest impact velocity tested (81 m/sec) where no reaction was observed. Two impact velocity dependent combustion modes were observed in the high speed motion pictures. No accelerating reactions were observed in either the motion pictures or the pressure gage data for the conditions tested. Traditional analytical porous bed combustion techniques were used in the evaluation of the pyrotechnic response under dynamic loading conditions. The NWCDDT porous bed code was used to model the response of the pyrotechnic power to mechanical stimulus. Calculations of the pyrotechnic powder were complicated by the rebounding of the initial compaction wave off of the end of the confining tube.
