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

A refined higher-order zig-zag model in conjunction with a new modified couple stress theory capable of capturing scale effect is proposed for vibration analysis of composite microbeams. The aim is mainly focused on the effects of transverse shear stresses on the accurate prediction of natural frequencies for composite microbeams. Differing from previous work, transverse shear stress satisfies the interlaminar continuity condition, whereas the higher-order derivatives of displacement variables have been eliminated by employing the three-field Hu-Washizu (HW) mixed variational principle. Moreover, accurate transverse shear stresses are introduced in motion equations by using Hamilton's principle, which can actively impact the accurate prediction of natural frequencies of composite microbeams. Within the framework of the variational formulation, the governing equation and corresponding boundary conditions can be obtained. The performance of the proposed model is tested by analyzing vibration behaviors of the simply supported multilayered composite microbeams. The effects of the material length scale parameters, the material constants, and layouts on the natural frequencies of the composite microbeam are completely investigated. The results show that the proposed model can accurately predict the scale effect of composite microbeams, whereas the models violating the continuity conditions of transverse shear stresses largely overestimate the natural frequencies of composite microbeams.
