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: 1.3 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: 1.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.7 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: 0.00023 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: 0.11 SJR: 0.244 SNIP: 0.521 CiteScore™:: 3.6 H-Index: 14

ABSTRACT

The paper presents the results of experimental and theoretical investigation of the mechanical properties of composite ceramics based on silicon nitride, reinforced with silicon carbide fibers. Composite ceramics samples reinforced with unidirectional fibers with a volume content of 10% were obtained using the 3D printing technology and manual lay-up method. The ceramic matrix contains up to 30% of porosity, and the average pore size is less than 1 μm. Flexural strength and the Young modulus of the pure and reinforced ceramics were determined in three-point bending tests. The results of experimental studies are compared with those of modeling. FE simulation of a porous matrix is performed based on realistic representative fragments generated using an overlapped solid grains model. Evaluation of the influence of fibers on the properties of unidirectional samples is performed on the basis of a simple slab model with regard to the porous matrix effective properties found in numerical simulations. It is shown that the experimental results for the effective elastic modulus of the composites agree well with the calculation results, but the strength of the experimental samples is 30% lower than that calculated.
