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

RÉSUMÉ

Inelastic modeling of composite materials is typically a very time-consuming task, even when the microscale material properties are taken into account in a simplified way, e.g., by a homogenization technique. In this paper a twofold improvement in computational homogenization that leads to more efficient and reliable analysis of elasticplastic metal matrix composites is presented. First, possibility of determination of the overall inelastic material properties on the basis of only one representative volume element (RVE) is verified. Second, an a posteriori homogenization error estimate is adopted for elasticplastic problems in order to control modeling accuracy and determine whether a single RVE analysis is in particular case a reasonable trade-off between accuracy and efficiency. Selected numerical experiments validate the proposed modifications.
