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

SINOPSIS

A multifield continuous model is adopted to investigate the mechanical behavior of heterogeneous materials made of short, stiff, and tough fibers embedded in a more deformable matrix. This continuum accounts for the presence of internal structure by means of nonstandard field descriptors. The constitutive relations, obtained by a multiscale approach linking the material description at different scales, depend on the geometry and the arrangement of the internal phases and include internal scale parameters, which allow taking into account size effects. A multiscale finite element technique has been used for obtaining the numerical solution of the multifield and the corresponding Cauchy model. The numerical results obtained on a sample fiber-reinforced composite show the effectiveness of the former in pointing out the influence of the size, shape, and orientation of the fibers on the gross behavior of the material.
