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: 0.2 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: 0.3 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: 0.00004 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: 0.08 SJR: 0.153 SNIP: 0.178 CiteScore™:: 1 H-Index: 12

RÉSUMÉ

THE article presents an analysis of steady-state creep in a variable-thickness rotating disc made of functionally graded composite containing linear and nonlinear distributions of silicon carbide particles in an aluminum matrix. The composite is assumed to creep according to a threshold stress-based law. The stresses and strain rates have been calculated in the FGM discs as well as in a similar composite disc but having uniform distribution of reinforcement. The presence of a linear or nonlinear reinforcement gradient in the composite disc leads to an increase in the radial stress over the entire disc radius, however, the tangential and effective stresses increase significantly near the inner radius but decrease towards the outer radius. A nonlinear FGM disc exhibits a relatively higher amount of increase or decrease in stresses than a linear FGM or uniform disc. The magnitudes of tangential and radial strain rates in FGM discs are significantly lower than in a uniform composite disc. An FGM disc, having nonlinear distribution of reinforcement, possess the lowest and relatively uniform distribution of strain rates, thereby, it is susceptible to lesser distortion.
