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

RESUMO

In the present paper, numerical simulation is developed in order to predict the structural failure of a damaged potting insert in a sandwich structure. To simulate the different materials, mechanical behaviors in compression and bending of the potting and honeycomb are firstly performed experimentally. A model of the sandwich specimen is divided into three steps: damage creation by indentation, removal of the indentor, and finally pull-through. Three different damage locations are investigated. To reduce the size of the numerical model only 1/4 of the specimen is simulated. The results show that the model is able to predict the structural failure of the sandwich specimen. Delamination in the upper skin is compared with the experiment. Moreover, honeycomb damage is successfully predicted numerically. Finally, matrix cracking of the upper skin is analyzed.
