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 problem of improved simulation of ultrathin rods, arising because of the need of explaining the known experimental data about a substantial dependence of the flexural rigidity of such ultrathin structures on their thickness when the thickness becomes commensurable with characteristic parameters of the material microstructure, is discussed. In order to simulate such effects in the theory of thin rods the gradient theories are used. The question of whether ultrathin structures really implement the scale effects that result in substantial modification of effective rigidity properties is considered. The analysis is made using correct applied versions of gradient theories as well as different approaches in formulating the applied theories of bending of rods, beginning with the variational and semi-inverse methods and ending with the asymptotic method. It is shown that the assertion on a hyperbolic dependence of effective rigidity of ultrathin rods on the thickness, actively discussed in the recent years, is fallacious.
