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 multiscale mesh-free formulation based on the reproducing kernel particle method (RKPM) is used to develop a damage model for ultra-high-performance concrete (UHPC). The damage evolution law is derived from the Helmholtz free energy, where the energy released from the cracked microstructure is equated to the homogenized macroscale response at the continuum level. In order to perform the microscale calculations for UHPC, the fracture energy of the UHPC must be determined. In this study, the fracture energy of a UHPC is experimentally determined by performing single-edge notched three-point beam tests. The fracture energy is required in order to perform physically based RKPM microscale calculations. The damage evolution law is then determined from the microscale calculations and applied to a quasi-static macroscale RKPM calculation. The multiscale framework is compared to a typical phenomenological damage model to show its ability to accurately reproduce softening behavior that exists under loading of a UHPC.
