Recueil de mécanique


The ''Recueil de mécanique'' abbreviated RDM is an international, peer-reviewed journal. It is edited by El-Wancharissi university of Tissemsilt. Starting from the vol.5 n°1 (January 2020) is accepted for review only English written manuscript. RDM is an open access journal which means that all content is freely available without charge. Users are allowed to read, download, copy, distribute, print, search, or link to the full texts of the articles in this journal without asking prior permission from the publisher or the author. Focus and Scope: The periodic covers a significant number of thematic. For illustration and not limited to the following topics are treated: -power plants (conventional and hybrid, stationary and on board); -thermal science; -thermodynamics; -fluid mechanics; -mathematical modeling of systems and processes;-renewable energy (solar, wind, geothermal, tidal powered, etc ...) processes and technologies; -mechanical contacts and tribology; -machines dynamics, vibration, acoustic and maintenance; -engineering; -aerospace engineering; -automotive engineering; -computational mechanics; -industrial and manufacturing engineering; -mechanical engineering; -...etc. In addition to original articles, the journal is also dedicating special issues to seminars and colloquium works. Peer Review Process: The ''Recueil de mécanique'' operates a double blind review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent by the editor or the associated editors to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. Publication Frequency: The ''Recueil de mécanique'' is published twice a year in December and July with two regular issues (not including special issues) and one volume per year. RDM is indexed in DOAJ Sherpa/Romeo, ULRICHSWEB and Copernicus databases.







Study of the lifespan of buried structures using the Weibull approach - case of the GZ1 gas pipeline "Hassi R’Mel - Arzew"

هواري علي,  بنزنين حميدو, 

Résumé: The steels of pipelines for the transport of hydrocarbons are stressed by damage phenomena, particularly by corrosion by soils. After detection of these failures by non-destructive testing such as ultrasound or by magnetic flux, the remaining time must be evaluated by a probabilistic approach. This work consists in evaluating the remaining service life of corroded pipes by Weibull approach over a distance of 70km from the GZ1 line. Inspection results showed peak corrosion depths with a rate of 10-30% of the thickness and two areas damaged by corrosion with a rate exceeding more than 70%. The different reliability parameters namely reliability function, failure function, failure rate, rated life and MTBF from MATLAB computer code were also determined and discussed.
