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

RÉSUMÉ

A methodology for determining residual stresses and strains in flat polymer composite panels reinforced by nanomodified whiskered fibers is suggested. In order to calculate the effective properties of the whiskered monolayer, an approach based on the model of multilayered cylindrical inclusion is used. The properties of the interfacial whiskered area are determined by the model of elliptical inclusions with chaotic orientation. The residual stresses in the panels are determined by a classical thermoelasticity model for layered composites. As an example, we consider a problem of residual stresses and strains in a carbon fiber-reinforced plastic panel reinforced by whiskered fibers with carbon nanotubes grown on its surfaces. The computations conducted show a practical possibility for eliminating the residual stress and strain in the material with different variants of reinforcement. It is also shown that the model suggested can be used to predict different whiskerization parameters that allow reducing anisotropy of the thermal expansion coefficients in composites.
