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: 1.2 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: 1.8 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

ABSTRACT

In our previous work we used high-speed imaging to experimentally study the impact of yield-stress fluid drops on pre-coated horizontal surfaces, observing impacts with different drop size, impact velocity, pre-coating thickness, and rheological material properties. Impact events were categorized and a single dimensionless parameter was introduced to reduce the regime map of behavior from four parameters down to one, the ratio of inertial to dissipative forces with proper geometric ratios. Here, we study more deeply the experimental data set, going beyond stick/splash categorization to examine quantitative measures of these impacts. Impact event duration time, material rebound height, maximum radial spread distance, and final crater diameter are presented as a function of the same dimensionless group that reduced the impact regime map. The ratio of inertial to dissipative forces reduces the description of these quantitative parameters and scaling law observations are reported.
