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

A multiscale approach to the nonlinear electromechanical analysis of piezoelectric and ferroelectric structural elements is presented. The multiscale modeling ranges from the unit cell scale, in which the phenomena of domain switching originate, and goes through the grain scale, the material point scale, the continuum scale, and up to the structural element scale. A multiscale approach for the numerical solution of the governing equations of the nonlinear structural model is also presented. This approach accounts for the loading history dependency and the nonlinearity of the ferroelectric behavior by implementing an incremental iterative procedure and separate discretizations for the grain, the material point, and the structure scales. A numerical example of a ferroelectric beam under combined bending, compression, and electrical loading demonstrates the various multiscale aspects of the model and, particularly, the influence of the domain switching on the response at the different physical and mathematical scales. The findings of the article designate the multiscale approach as a meaningful step toward the implementation of ferroelectric materials in advanced smart structures with enhanced capabilities.
