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

SINOPSIS

The paper presents numerical results for a two-scale damage model accounting for mixed-mode propagation of microcracks. A time-dependent propagation criterion is assumed for microcrack growth and a kinking direction criterion based on the maximum of the energy-release rate is used. The macroscopic damage evolution laws are obtained by homogenization based on asymptotic developments. A numerical procedure based on finite elements is developed for the two-scale model and simulations illustrating the structural response are presented. A priori microscopic computations increase the efficiency of the computational model at the scale of macroscopic structures. The resulting homogenized behavior involves softening and localization of damage. Direct links between macroscopic damage evolution and microscopic propagation of micro-cracks are established within the two-scale model.
