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: 0.2 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: 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: 0.00004 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: 0.08 SJR: 0.153 SNIP: 0.178 CiteScore™:: 1 H-Index: 12

Краткое описание

Within the framework of the spatial theory of rigidity, two approaches to investigation of free and forced axially symmetric vibrations of anisotropic cylindrical shells have been developed with account for energy dissipation. They are based on the division of the given shell into a number of constituent shells over the thickness. In the first approach, for approximation of sought functions over the thickness polynomials are used, in the second, their distribution over the thickness on the basis of analytical solution of the corresponding system of differential equations. In the plan of the construction the sought functions are presented in the form of trigonometric functions. The necessity of developing two approaches is attributed to the fact that they have inaccuracies of approximation and arithmetic calculations, which are especially seen in calculation of forced vibrations at the frequencies close to the resonance ones. The calculation by two methods serves as the proof of its validity. An analysis of shell's behavior in free and forced vibrations at frequencies close to the resonance ones is made.
