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

摘要

In the present paper, numerical simulation is used to analyze the composite tooth failure of composite chainring at a low-velocity/low-energy impact. To reduce the size of the numerical model only 7 teeth are simulated. In order to validate the numerical simulation, impact force-displacement curves are compared to experimental results obtained on the same specimens used in the simulation. Damage size and residual displacement are also compared with the experiments. As the teeth geometry cannot be modified due to the chain, the effect of fibers type is studied in order to avoid teeth failure. The results show that delamination is the first damage followed by fibers failure. Moreover, the fibers type has no significant influence on the tooth behavior under impact. Finally, composite material presenting a low Young modulus and a large elongation is investigated and tooth failure is avoided.
