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

ABSTRACT

The paper develops an analytical-numerical algorithm for estimating the relaxation kernels of a dispersed viscoelastic composite based on the data of experimental measuring the properties of the initial material and the method of asymptotic homogenization applied to the equations of thermoviscoelasticity. Here, a viscoelastic analogy is used that makes it possible to obtain a description of the thermoviscoelastic characteristics of a filled composite material by the equations of the theory of elasticity with rapidly oscillating coefficients of complex value that depend on spatial coordinates and temperature. For the problem on a cell with the conditions of a periodic jump, a special analytical-numerical method has been developed for its solution, based on approximations by a system of functions that exactly satisfy the equations and contact conditions on the interfaces. The conditions of a periodic jump are then solved using the generalized Trefftz method for the equations of the theory of elasticity with complex coefficients. The paper presents examples of using the developed method to determine the time modulus and loss tangent of styrene−butadiene rubber depending on the volume fraction of the filler.
