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

Краткое описание

The processes occurring in metallic specimens under the impact of electric high-density current are considered. The electric and temperature fields and their influence on the phase transformation and stress−strain state in the vicinity of microdefects in the form of plane cracks are studied. A mathematical model of the effect of an electromagnetic field on the predamaged elastic-plastic material with an ordered system of defects is proposed. The model accounts for melting and evaporation of material and the dependence of its all physical and mechanical properties on temperature. The problem is solved by finite elements method with the use of an adaptive mesh on the basis of an arbitrar Euler−Lagrange method. The numerical modeling has shown that in the vicinity of microdefects a high-density current with large field gradients arises, which leads to intense local heating accompanied by thermal expansion and melting of the metal on the tips of the microcracks. This results in high compressive stresses in the vicinity of microcracks, intense plastic flow of the material and, as a consequence, in the clamping of microcrack sides, decrease in microcrack length, and in the ejection of the molten material into the crack. As a result, the microcrack is completely healed. The numerical results obtained by the proposed model agree with experiment.
