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

ABSTRAKT

In this paper, we have developed a genetic model to evaluate the influence of thermal stress on the transverse damage of the fiber−matrix interface hybrid composite material Glass_carbon/Epoxy. This genetic approach is based on the Cox equation and the probabilistic models of Weibull: damage of the fiber and damage of the matrix. The model takes into account the effects of temperature that result in the gradual deterioration of the fiber−matrix interface. This study has shown the influence of heat stress beyond a critical threshold of transverse damage to the interface, and also showed that damage to the interface of the carbon/epoxy composite material is greater compared with that of the hybrid composite glass_carbon/Epoxy under the effect of the same thermal stress. Our simulation results are in good agreement with the experimental results conducted by Vasconcelos et al. (2001). Therefore, our findings revealed that the model worked well with the phenomenon of damage to unidirectional composite and hybrid composite materials.
