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: 0.7 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: 0.7 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: 0.1 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

要約

A numerical viscoelastic plastic constitutive model is proposed to simulate the non-linear behavior of a granular energetic material under quasi-static conditions. This model is restricted to an isotropic framework. It includes a damage evolution and two separate uncoupled failure criteria. The yield criterion is parabolic and based on the two first stress invariants in order to take into account the pressure. The plastic flow rule is non-associated and is introduced through a compaction/dilatancy parameter. The viscoelastic part is described by a generalized Maxwell model. The model is calibrated using an extended experimental database that includes a dynamic mechanical analysis test, cyclic compression, and tensile tests with relaxation and recovery stages. Some compressive tests include a confinement pressure. The parallel structure of the model allows for separate identification of the elastoplastic and viscoelastic parts. The model constitutive equations and its implementation in a commercial finite-element code are presented. The model validation is based on a three-point bending test and a Brazilian test. The simulations show good correlation with the uniaxial experimental results. Some discrepancies are observed between the experimental and simulated results for the Brazilian test, which are related to a biaxial load case. This highlights the induced damage anisotropy observed from cyclic tests, which is not taken into account in our model.
