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

要約

This manuscript presents an extended finite element method (XFEM) approach to capture the interactions between fibers in short fiber reinforced composites. Short fiber inclusions are incorporated into the XFEM framework as deformable elastic zero measure objects. Two separate enrichment functions are employed to account for both the presence of fibers within the composite domain and to idealize the progressive debonding along fiber matrix interfaces. This study investigates the accuracy characteristics of the formulation when multiple fiber enrichments and interface debonding enrichments lie within a single element. Accurately capturing multiple enrichments in a single element is particularly important for modeling the failure process of fiber reinforced composites with a significant amount of discontinuous fibers with high aspect ratios. The performance of the proposed XFEM model is assessed by comparing model predictions to the direct finite element method for various interacting fiber configurations. The numerical verification studies indicated that the proposed model displays high accuracy and captures the debonding interactions at fiber-matrix interfaces.
