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

SINOPSIS

In this work, a numerical model has been developed to predict the damage and failure of an aircraft windshield incurred by high-speed repeated bird impacts. Finite element (FE) simulations were performed by implementing the numerical model in explicit FE solver ANSYS AUTODYN. A rate-dependent elastoplastic material model with the maximum principal stress failure criterion and Mie−Gruneisen equation of state (EOS) model with the tensile failure criterion were adopted to model the damage of windshield and bird, respectively. The model successfully predicts the damage initiation and complete failure of windshield at different impact velocities. The maximum normal displacement and equivalent stress at different positions on the windshield were determined and compared for a single and multiple impacts. On the basis of numerical results, the limiting impact velocity, critical number of impacts, and the weakest portion on the windshield were also determined. The results show that at higher impact velocity, multiple impacts prove fatal to the windshield structure. The windshield that withstands a single bird impact is vulnerable to fail under successive impacts.
