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

In this paper, an efficient multiscale computational method is presented for the coupling field analysis of heterogeneous magneto-electro-elastic media. In this method, the displacement, electric, and magnetic potential multiscale base functions that contain the coupling effects between different physical fields are firstly constructed. By virtue of these numerical base functions, the effective material properties of the heterogeneous media could be reflected to the macroscopic scale. Thus, a single heterogeneous magneto-electro-elastic unit cell can be equivalent into a coarse element and the original multiphysics coupling boundary value problem could be solved on the macroscopic scale directly, which will save a significant amount of computing time and resources. According to the macroscopic solutions, the microscopic mechanical, electrical, and magnetic responses can be further recovered by downscaling computation using the above-constructed multiscale base functions. Finally, several numerical examples are carried out to illustrate the effectiveness and correctness of the proposed multiscale method. The comparison between the present results on the macroscopic coarse-scale mesh and those calculated by the standard FEM on the microscopic fine-scale mesh indicates that the proposed multiscale method not only can provide accurate coupling responses of heterogeneous electro-magneto-elastic media but also has high computational efficiency.
