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

Краткое описание

This paper describes the development of a unit cell for concrete structures. Executing a multiscale analysis procedure using the theory of homogenization requires solving a periodic unit cell problem of the material in order to evaluate the material macroscopic properties. The presented research answers that need by creating a concrete unit cell through using the concrete paste generic information (i.e., percentage of aggregate in the concrete and the aggregate distribution). The presented algorithm manipulates the percentage of the aggregate weight and distribution in order to create a finite element unit cell model of the concrete to be used in a multiscale analysis of concrete structures. This algorithm adjusts the finite element meshing with respect to the physical unit cell size, creates virtual sieves according to adjusted probability density functions, transforms the aggregate volumes into a digitized discrete model of spheres, places the spheres using the random sampling principle of the Monte Carlo simulation method in a periodic manner, and constructs a finite element input file of the concrete unit cell appropriate for running a multiscale analysis using the theory of homogenization.
