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

ABSTRACT

The aim of the study is to develop a stiffness modification technique that considers the effects of local deformations/damages within the predictor step of iterative global-local analysis. The procedure is based on internal springs introduced in a beam element formulation whose constants are obtained according to the force vs. displacement results of the global-local analysis. Within the beam element formulation, strong discontinuities are introduced in the form of an internal enrichment considering additional local degrees of freedom associated with the deformations of local springs. Determination of the spring constants introduced in this study is an inverse problem, as given independent end-displacements and end-forces, corresponding spring stiffness terms are sought. Discussions on the heuristic nature of this problem are included and a regularization option is introduced to give rise to a unique solution for the problem. Nevertheless, it is shown that by using the proposed approach the number of iterations can be significantly reduced within the iterative global-local analysis algorithm. In the corrector step of the global-local analysis a local membrane finite element model is used to obtain the internal stress field.
