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: 1.7 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: 1.9 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: 0.5 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: 0.0007 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: 0.5 SJR: 0.584 SNIP: 0.676 CiteScore™:: 3 H-Index: 25

ABSTRACT

When cracks propagate under random loading, different realizations of the loading process lead to different histories of crack growth.Within all possible realizations of the random load process, the so-called design-point excitation represents that particular realization that most likely leads to failure (e.g. unstable crack growth). In this paper, the design-point excitation for random crack propagation is found under narrow-band load processes. The solution involves a spectral representation of the load process, rain-flow counting of the resulting stress ranges, crack growth computation by means of the Paris Law, and solution of a reliability problem by FORM (First Order Reliability Method). The FERUM software is used in the reliability analysis. The design-point excitation is shown to exist for narrow-band load processes. Some considerations are presented with respect to the form of this excitation. So far, no convergence has been obtained for broad-band processes.
