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

ABSTRACT

The fracture behavior of structural steel S355 is observed with a 3D digital image correlation (DIC) system and simulated with the Gurson-Tvergaard-Needleman (GTN) model. Crack propagation and strain field variation on the surface of a side-grooved compact tension [C(T)] specimen is captured with the DIC system, and the shape of the stable fracture region is obtained from macroscopic optical images of the fracture surfaces of the specimen. 2D and 3D GTN models are used to simulate the damage of a C(T) specimen. It is concluded that very similar force vs. crack opening displacement (F-COD) curve along with the morphology of stable crack extension region can be obtained from the GTN simulations.
