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

摘要

General approach to solution of axisymmetric problems on instantaneous loading of an elastic half-space is considered in the present article. Mentioned approach is based on the use of the Laplace's transform with respect to time and the Hankel's transform with respect to spatial coordinate. When originating from analysis of the functions-images it became possible to represent the displacements on the surface of half-space as multiple integrals from functions of real variables. Particular types of loads were investigated, namely, the point load (the Lamb's problem), the Hertz's distribution, and the load arising under the smooth plane stamp in the static contact problem. It has been shown that for any distributed normal load, instantly applied to a boundary of half-space, the normal displacements in an observation point become equal to their static values just after the moment when the Rayleigh's wave generated by a most distant point of the load application passes. Also, the singularities were investigated, arising in a displacement field on fronts of the Rayleigh's waves, which move a from boundary of loading zone. Obtained results give the possibility to make conclusions, useful when considering the non-stationary contact problems.
