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: 1.5 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 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

RÉSUMÉ

When considering the durability of structures with cracks it is necessary to take into account the possibility of crack surface contact. Indeed, under arbitrary loading of structures there is no guarantee that the cracks will be completely opened. Complete or partial closure can take place if the material is under compression. The crack surface contact leads to changes in the stress and deformations within the structure and influences the conditions of crack growth and the lifetime of structures. The problem of a penny-shaped crack closure induced by heat sources is considered. Analytical results are obtained by means of Hankel transforms and the corresponding dual integral equations. Closed-form solutions for heat flux across the crack surfaces and for the aperture of the crack are obtained. The solutions are illustrated graphically for cracks with different initial openings. The crack contact zones as functions of the distance between the heat sources and the crack are shown.
