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

ABSTRACT

In this study, the quasistatic mechanical behavior of Nylon-6/silica nanocomposite is examined through a hybrid experimentalcomputational approach. Two factors, particle aggregation and the interphase layer, which affect the properties of such nanocomposites, are investigated. The polymer matrix behavior in the bulk and interphase regions is described using a hyperelastic material model calibrated by experimental tension test results conducted at room and reduced temperatures. The characteristics of the interphase and bulk polymer identified are used in a finite element representative volume element (RVE) to study the effects of particle aggregation and the presence of the interphase layer. The degree of particle dispersion in the RVE is defined using a parameter termed the degree of aggregation. Simulation results show that in the absence of an interphase layer, the mechanical properties of nanocomposites are independent of the degree of aggregation. However, with the presence of an interphase layer, the aggregation of nanoparticles decreases the mechanical properties of Nylon-6/silica nanocomposite.
