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

摘要

We consider a linearly thermoelastic composite medium of arbitrary anisotropic constituents, which consists of a homogeneous matrix containing a statistically homogeneous random set of inclusions of any shape, orientation, and inhomogeneous micro structure. We use the main hypothesis of many micromechanical methods, according to which each inclusion is located inside a homogeneous so-called "effective field," accompanied by the quasi-crystalline approximation describing the inclusion interactions. We estimate effective elastic properties of composites and statistical averages of stresses, which are in general inhomogeneous in the inclusions. The proposed analytical—numerical method is efficient from a computational standpoint and is based on the use of the finite element analysis implemented for the one-particle problem in the infinite-homogeneous matrix with forthcoming incorporation of the stress concentrator tensors found in the known analytical homogenization scheme of micromechanics described above. The method is presented for both two- and three-dimensional problems, but the numerical examples are carried out just for plane strain and plane-stress problems.
