COMPORTEMENT A LA RUPTURE ET CARACTERISATION MECANIQUE DE COMPOSITES POLYESTER-FIBRES DE VERRE

Composite materials find extensive usage in industrial applications. Howeer, they are susceptible to gradual damage over time. In this study, we explored the cracking processes in jute fiber-reinforced composite sheets subjected to uniaxial tension at varying displacement speeds (10, 20, and 30 mm/min) using Abaqus software. The composite plate dimensions are 25×35×10 mm³, with a 7 mm crack length. Our findings indicate that crack propagation in vehicle plates is influenced by mechanical properties relative to load, specifically through increased travel speed. We observed stress concentration around the crack, and the displacement speed significantly affects crack behavior. The cohesive J-integral was derived through finite element analysis, revealing a 90.90% relative error in the mean absolute value ΔJ across the five integral paths for the two sample types. Subsequently, five potential end conditions were assessed for further analysis, considering different boundary conditions: Simply supported (SSSS), two opposing sides clamped (SFSF), Clamped-Simply-ClampedSimply (SCSC), two opposing sides clamped (CFCF), and all sides clamped (CCCC). Additionally, three different types of tensile actions in the y-direction were considered

Abstract This paper presents a numerical study of natural convection in an annular cavity filled with a hybrid nanofluid under the influence of a magnetic field. This study is significant for applications requiring enhanced thermal management, such as in heat exchangers, electronics cooling, and energy systems. The inner cylinder, equipped with fins and subjected to uniform volumetric heat generation, contrasts with the adiabatic outer cylinder. This study aims to investigate how different nanoparticle combinations (Fe3O4 with Cu, Ag, and Al2O3) and varying Hartmann and Rayleigh numbers impact heat transfer efficiency. The finite volume method is employed to solve the governing equations, with simulations conducted using Fluent 6.3.26. Parameters such as volume fraction (ϕ2 = 0.001, 0.004, 0.006), Hartmann number (0 ≤ Ha ≤ 100), Rayleigh number (3 × 103 ≤ Ra ≤ 2.4 × 104), and fin number (N = 0, 2, 4, 6, 8) are analyzed. Streamlines, isotherms, and induced magnetic field contours are utilized to assess flow structure and heat transfer. The results reveal that increasing the Rayleigh number and magnetic field enhances heat transfer, while the presence of fins, especially at N = 2, may inhibit convection currents and reduce heat transfer efficiency. These findings provide valuable insights into optimizing nanofluid-based cooling systems and highlight the trade-offs in incorporating fins in thermal management designs. Keywords: hybrid nanofluids; magnetic field; natural convection; annular cavity; fins; volumetric heat generation

ABSTRACT Studies on Ferrite/austenite stainless steels are still in progress because of the difficulties related to their two-phase structure. Since it is from the relative concentration of the phases; their distribution and their individual physic-chemical properties determine the mechanical characteristics of two-phase systems. Therefore, the relationships between the phases are still poorly known. The improvement of the mechanical and physical properties of these materials, is conditioned by a better knowledge of their structures and connections, and one must pass obligatorily by the implementation of adapted experimental methods. In this study we propose to better know in the first stage the aspect of the residual stresses In this study, it is better to know, at first, the aspect of the residual stresses which are important in the use of materials because they affect significantly the conditions of their operation. The determination of these residual stresses by the X-ray diffraction method has become a well-controlled technique, but its application to the study of two-phase materials remains more or less difficult. In the present work, we want to make the distinction and the behavior of an austenitic-ferritic in a chlorinated environment since it is in this type of environment that the majority of the cracks of stainless steel in service occur. The development of the nuclear industry has also revealed other forms of stainless steel cracking even in neutral environments, with very little solute content, or even in water that is considered pure. For the distinction of the behavior of these types of steel, we presented the studied material, with the indication of its characteristics; the areas of its use and the problems associated with the preparation of samples for testing. Then we studied the methods of carrying out the manipulations and the ways used to measure the phase dosage, the radio crystallographic elastic constant and the residual stresses. And finally the presentation of the results obtained and their discussion to draw, finally, the conclusions. Key words : Austenitic-ferritic stainless steels; volume fraction; residual stresses; elastic constants; ferric phase; austenitic phase.

Abstrait: Protection cathodique par courant imposé couplée à une protection passive ; nécessitent le contrôle et la maîtrise de toute une série de paramètres lors de son fonctionnement. La mauvaise protection cathodique mal maîtrisée provoque divers défauts sur les revêtements. Ce travail montre que la distribution de potentiel dépend du contrôle précis d'un certain nombre de paramètres caractéristiques tels que le milieu, l'environnement et les outils de protection utilisés... Pour l'application de la technique de protection cathodique, il faut également prendre en considération : la valeur des courants imposés, la nature du terrain, la nuance du matériau des canalisations, le type de revêtement, les dimensions et emplacements des déversoirs qui sont toutes les tailles de son implantation. La répartition acceptable du potentiel de protection le long de l'ouvrage dépend essentiellement de l'optimisation des emplacements et des valeurs des résistances de terre (déversoirs anodiques), et surtout de la valeur du coefficient d'atténuation, qui est fonction de la résistance de l'isolation et donc de l'état du revêtement. L'augmentation de la résistance d'isolement provoque l'affaiblissement du facteur d'atténuation, et donc une plus grande plage de retrait. Au contraire, un facteur d'atténuation plus important, la portée du soutirage est réduite et se traduira par une augmentation des stations de soutirage réparties le long des canalisations lorsqu'il s'agit d'une structure avec une faible valeur de la résistance d'isolement, d'où la nécessité d'un contrôle optimal de l'état du revêtement et contrôle du potentiel de protection.

Manuscripts should Quarries and mines that exploit hematite ore Fe2O3 usually have a large quantity of waste rock with low iron content, stored in the slag heaps of quarries or mines without enrichment. This work consists in finding solutions to this product to make it more or less usable in industries. After chemical and mineralogical analysis of the whole product, the large percentage of existing chemical elements is the hematite ore Fe2O3 which has a low iron concentration. To improve its iron content, it must be treated by chemical and hydro mechanical processes that are economically viable. Since it remains in the product heap, it will be degraded in the open air of the quarry by atmospheric chemical reactions. A certain amount of this stockpile is sampled at different locations in a heap to distinguish the chemical elements of the dominant product. The search for good enrichment techniques of these materials after their homogenization led us to choose among the main separation operations, those based on the difference of densities obtained by suspension in granulated Ferro-solutions composed of silicon and magnetite. From the results of the gravimetric separation, three fractions were obtained: an iron-rich fraction; a medium fraction; an iron-poor fraction <10%. According to the magnetic properties analysis, as a semi-separated product, the medium iron fraction will undergo a new enrichment sequence by high magnetic field separation

The high-gradient magnetic separation process is a technique used in heavy industries, particularly steel mills, to extract magnetic particles from mixtures. The difficulty of separating the slightly magnetic particles from the nonmagnetic ones lies in the distribution of the magnetic field and the fineness of their class to be separated. A use of different separation matrix profile is implemented, making it possible to act on the value of the gradient of the inhomogeneous magnetic field. Different matrixes are tested and the results obtained experimentally allows to choose the most efficient matrix form in the operation of extraction which increased by 11% in magnetic fraction yield, 15% iron content and 17% of extraction degree relative to the John’s matrix. This matrix used is consistent with that cited in literatures. The separation technology used can extend its useful application to small particles from very weakly magnetic materials. Its exploitation will result in the method of reducing the degree of pollution and improvement the process of extraction of minerals that has an impact on the environment and on human health as a result a high level of extraction.

La plupart des activités industrielles reposent sur l’extraction des minerais et des produits minéraux, et les activités extractives s’exercent dans presque tous les pays du monde, sous une forme ou une autre. Les industries extractives ont d'importantes répercussions sur l'économie, l’environnement, le travail et les aspects sociaux.Au terme d’une période d’augmentation des prix des produits de base exceptionnellement, les principaux acteurs de l’industrie minière prévoient un ralentissement de la croissance et une éventuelle diminution de la production et de l’emploi dans le secteur. Si cette tendance se confirme, il conviendra de trouver des solutions durables pour les mines sinistrées et leurs travailleurs.

Dans ce travail on à montré la variation des caractéristiques du champ magnétique par rapport aux formes d’une dent de pôles aigus aimantés sous de différents angles de travail .On a constaté qu’avec la diminution de l’angle de travail de la dent, la non homogénéité du champ magnétique augmente ce qui fait augmenter les forces magnétiques et leurs concentrations dans des zones bien déterminées des pôles aimantés. Après plusieurs expériences sur les formes des pôles aimantés ,on est arrivés aux formes finales de caractéristiques suivante voir la Figure si dessous .Les analyses profondes de ces formes nous ont conduit à connaitre les zones de travail des pôles qui ont de grandes concentrations du gradient du champ magnétique qui se trouve chaque fois aux sommets des dents constituants les de matrices des séparateurs a haut gradient. Les recherches sur les théories et les pratiques du champ magnétique en fonction de leurs formes ont montrés qu’ils présentent des difficultés énormes, en séparation magnétique .Mais leurs avantages sont très efficace si on maîtrise l’orientation de leurs lignes équipotentielles pour la séparation magnétique des particules très fines. Ces avantages sont caractérisés par l’ouverture de la fraction magnétique pour pouvoir lui supprimer les impuretés non magnétiques pendant l’opération de désaimantation.
