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

要約

A basic concept in engineering design is a damage theory which is obtained as a physically natural justification in the framework of peridynamics. The basic feature of the peridynamic model considered is a continuum description of a material behavior as the integrated nonlocal force interactions between infinitesimal material points. In contrast to the classical theories, the peridynamic equation of motion introduced by Silling is free of any spatial derivatives of displacements. The material points interact with each other directly across finite distances through central forces known as "bonds". The damage concept is introduced by permitting these bonds to break irreversibly. A peristatic bar with periodically distributed damage is analyzed by a generalization of the classical locally elastic computational homogenization to its peristatic counterpart. One introduces the new volumetric periodic boundary conditions at the interaction boundary of a representative unit cell whose local limit implies the known locally elastic periodic boundary conditions. The applicability of local elasticity theory is demonstrated for description of effective elastic behavior of this bar. Estimation of the effective moduli of a damaged medium (initially homogeneous) as the functions of the local damage, damage functions, and micromodulus profiles are obtained. One analyzes either the translation invariant damage functions or non-translation-invariant ones (which can be considered as a model of damage localization).
