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

This manuscript presents a multi-yield surface model to idealize the mechanical behavior of viscoplastic solids subjected to cyclic loading. The multi-yield surface model incorporates the evolution of nonlinear viscoplastic flow through a piece-wise linear hardening approximation. A kinematic hardening law is employed to account for the evolution of backstress with respect to the viscoplastic strain rate. The new backstress evolution strategy is proposed to ensure that all yield surfaces remain consistent (i.e., satisfying collinearity) throughout the viscoplastic process. The multi-yield surface model is coupled with viscoelasticity to approximate the relaxation behavior of high-temperature metal alloys. The model is implemented using a mixed finite element approach. The capabilities of the proposed approach are demonstrated using experiments conducted on a high-temperature titanium alloy (Ti-6242S) subjected to static, cyclic, and relaxation conditions.
