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 paper presents an experimental analysis to determine the teeth failure of noncircular composite chainring. A noncircular carbon/epoxy chainring with a specific stacking of 11 plies is studied. In a first step, a quasi-static tensile test is realized on the chain and on the chainring to determine their strength. As the damage of composites is a major concern, as a second step the low-velocity/low-energy impact drop tests are performed. Five levels of impact energy are investigated in order to study the energy effect on the teeth damage, and the damage localization is analyzed using C-Scan. Quasi-static results show that the metallic chain fails first. Experimental impact results reveal that teeth damage is presented only for an impact higher than 1.6 J. Finally, the total teeth failure appears for an energy close to 2.5 J.
