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: 1.4 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: 1.3 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: 2.2 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: 0.00034 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: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

摘要

To analyze deformation of geomaterials with space and time, two modeling methods are described: a dynamic method where fracture is taken into account explicitly with special emphasis on crack system formation, their coalescence, etc.; a quasi-static method where specific consideration is given to the influence of temperature at quasi-static loading. The constitutive equations used take into account the dilatancy effects, damage accumulation, and degradation of mechanical properties. Consideration is given to calculation examples of deformation and damage localization observed at various scales, namely, from small laboratory samples up to huge crustal elements. In the framework of the dynamic approach, the formations of bands of localized deformation in the vicinity of a failed inclusion and within a medium layer in shear are obtained. Features of strain localization for several geological models of the lithosphere are presented. In the framework of the quasi-static approach, the formation of ring-like structures under cooling of a heterogeneous media is discussed. These problems are considered as the problems of mesoscale since essential meso-constituents are taken into account.
