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: 1.3 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: 1.7 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: 0.7 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: 0.00023 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: 0.11 SJR: 0.244 SNIP: 0.521 CiteScore™:: 3.6 H-Index: 14

ABSTRACT

The paper deals with modeling of an unusual dependence of the mechanical properties of polyurethane-urea (PAU) cross-linked elastomer containing 10 vol.% polyamide-6 (polycaprolactame) of the concentration of nanomodifier - single-wall carbon nanotubes (CNT). This elastomer picks up unusual properties after introduction of an extremely small amount of CNT. A relatively small mass fraction of nanotubes in the composite changes from zero to 0.018%. Results of the experiment show that at a mass fraction of nanoinclusions of about 0.002% a substantial and clearly defined growth of practically all mechanical characteristics, including the elasticity modulus and limiting stresses, is observed. In this case, limiting deformations change slightly. In the work, the effect of anomalous variation of the Young modulus is modeled using the gradient model of interphase layer.
