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

RÉSUMÉ

One interesting topic in multibody dynamics is how a reference frame is attached to a moving deformable body. Two known forms of reference axes are the nodal-fixed and the mean axes frames; the former is commonly used in structural finite element modeling, and the latter is known as a floating frame. In this article we introduce a new reference frame based on the principal axes that is also a form of floating frame. The equations of motion for a deformable body are derived first, and then the conditions for different types of reference axes are implemented. Next, the equations of motion for a rigid-deformable multibody system are constructed, where the deformation variables are kept in the nodal space. Through several simulation examples, some phenomena associated with each type of reference frame are discussed.
