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: 1.4 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 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: 2.2 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: 0.00034 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: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

ABSTRACT

Various problems of heterogeneous multiscale systems are analyzed from the variational point of view. Since many composite materials consist of different components, the optimal functions may experience discontinuities along internal interfaces. In many instances, the locations of the interfaces is not a priori known, but must instead be determined by the variation principle. One of the first attempts of analyzing such problems was presented by Gunther, which we advance in several directions. In the Gunther problem, the integrand q (x, w, Δw)depends on the spatial gradients of a scalar field w (x). For one of the simplest types of discontinuities sort, Gunther found the formula of the first variation and established the appropriate extension of the Weierstrass-Erdmann transversality conditions. We establish some explicit solutions of the boundary value problems associated with the Gunther problem and derive the expression for the second variation.
