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

Separation of two particles is characterized by a magnitude of the bond energy, which limits the accumulated energy of the particle interaction. In the case of a solid comprising many particles, there exist a magnitude of the average bond energy, the failure energy, which limits the energy that can be accumulated in an infinitesimal material volume under strain. The energy limiter controls material softening; the softening indicates failure. Thus, by limiting the stored energy density, we include a description of material failure in the constitutive model. When the failure energy, that is, the energy limiter, is introduced in the constitutive model, it can be calibrated in macroscopic experiments. Traditional material models do not have energy limiters, and they allow for unlimited energy accumulation under the strain increase, which is unphysical because no material can sustain large enough strains without failure. We review the applications of the new approach based on the use of the energy limiters to failure of soft biological tissues and fracture of brittle materials. In addition, we consider new developments concerning the rate-dependent failure in solids and the drop of viscosity in fluids.
