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

This paper presents an adaptive multilevel computational model for the multiscale analysis of composite structures with damage due to fiber/matrix interfacial debonding. The method combines continuum damage modeling with displacement based FEM with a microstructurally explicit modeling of interfacial debonding by the Voronoi cell FEM (VCFEM). Three computational levels of hierarchy with different resolutions are introduced to reduce modeling and discretization errors due to an inappropriate resolution. They are (a) level-0 of a pure macroscopic analysis, for which a continuum damage mechanics (CDM) model is developed from homogenization of micromechanical variables that evolve with interfacial debonding; (b) level-1 of a coupled macroscopic-microscopic modeling to implement adequate criteria for switching from macroscopic analyses to pure microscopic analyses; and (c) level-2 regions of a pure microscopic modeling with explicit interfacial debonding. The CDM model for a level-0 analysis is constructed from rigorous VCFEM-based micromechanical analysis of the representative volume element (RVE) followed by homogenization. A numerical example of a composite laminate with localized loading is solved to demonstrate the limitations of CDM models and to demonstrate the effectiveness of the multiscale approach in predicting failure due to interfacial debonding.
