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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

Краткое описание

Properties of normal waves in the thin-walled elastic cylinder filled with an ideal liquid are considered. The analysis is carried out in a wide range of frequencies. To describe the wave field in the elastic cylinder the complete set of equations of the dynamic theory of elasticity is used. It allows to study comprehensively the effects of interaction between waves in an elastic body and liquid. The basic attention is given to the cases concerning thin cylinders. The arrangement of numerical calculation data is carried out on the basis of known properties of some partial subsystems. Manifestation of the interaction effects and physical properties of normal waves in compound waveguide become sufficiently informative when the empty elastic cylinder and cylindrical acoustic waveguides with soft or rigid external boundaries as partial subsystems are chosen. Using the soft boundary model is justified in case of a thin-walled elastic cylinder and concerning low frequencies. At increase of rigidity of the cylinder or increase of frequency the waveguide with rigid wall is more suitable as a partial subsystem. The detailed analysis of the kinematic and power characteristics of normal waves is given. Their change depending on geometrical and physical parameters shows the role of the effects of elastic-liquid interaction in compound waveguides. Special attention is given to the lowest normal waves having the special properties and being most strongly the subject of the influence of the interaction between the solid and fluid parts of the waveguides.
