Recueil de mécanique


Description

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.

Analytical Solution for Free Vibration Analysis of Plates Functionally Graded FGP with Porosities

Merdaci Slimane, 

Résumé: In this paper, an analytical solution for the analysis of the free vibration of plates in functionally graded material (FGM) is presented, considering the porosities that can occur inside the materials with gradient properties (FGM) during of their manufacture. A method based on high order theory will be presented to study the free vibration of FGM plates. The proposed theory contains four unknowns unlike other theories. The governing equations are obtained through the Hamilton’s principal and the closed form solutions in terms of natural frequencies are obtained by using Navier technique. The numerical results obtained through the present analysis are compared with the ones available in the literature. The effects of various parameters, such as thickness ratio, gradient index, and porosity factor on the free vibration of FGM plates are all discussed.

Analysis of the Hardness of Aluminum by Instrumented Micro Indentation

حبيبي سمير,  سمسوم جمال الدين,  مزوغ عبد النور, 

Résumé: La dureté des matériaux est une propriété informative. Une méthode largement utilisée pour mesurer la rigidité et la résistance mécanique des surfaces est l’essai de dureté. L’effet de taille en indentation (I.S.E) est un aspect déterminant pour caractériser la dureté d’un matériau, inhérent à l’origine historique du test d’indentation lui-même. Ce phénomène est tributaire de la macro dureté qui correspond à la dureté obtenue par l'application d'une charge infinie. Et, qui est susceptible de décrire l'étendue de la variation de dureté induite par la taille de l'empreinte. La présente recherche se focalise sur l’étude comparative entre la dureté Martens et la dureté d’indentation et mettre en œuvre les avantages et les atouts d’exploitation des données de l’indentation instrumentée en matière de caractérisation mécanique des matériaux.
