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: 0.2 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: 0.3 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: 0.00004 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: 0.08 SJR: 0.153 SNIP: 0.178 CiteScore™:: 1 H-Index: 12

要約

In this paper, free vibration analysis of non-uniform sandwich beams with an elastic core is investigated. For the analysis, the element-free Galerkin (EFG) method and Galerkin formulation for two-dimensional elasticity problems are considered. The EFG method is one of the popular meshless methods. The penalty method is used for modeling the interface between the face sheets and the core in the sandwich beam. To free vibration analysis of non-uniform beams, a mathematical model has been presented. Using the similarity of materials for the face sheets and core, applicability of the model is tested. To show the accuracy of the presented mathematical modeling in respect to the numerical method, the results for uniform and non-uniform elastic beams have been compared with investigations. Then, the first ten natural frequencies of a non-uniform sandwich beam with an elastic core using the EFG and finite element methods has been calculated, good agreement has been demonstrated.
