    Thermodynamic analysis of a condenser vacuum from the central Ras-Djinet
    (Université M’Hamed Bougara Boumerdes : Faculté de Technologie, 2017) Rahmani, Abdenour; Rial, Soumia; Djedid, T.(Promoteur)
    In this Work he studied the influence of the temperature and flow of sea water, therefore the inlet air,exchange surface,impassibility on the vacuum of the condenser. We have applied the thermal NUT method in order to evaluate the thermal exchange of the gas condenser. And we have realized a thermodynamic analysis of the overall water vapor circuit.We found that the temperature of sea water increases, the condensation temperature increase while the pressure of the condenser of the cycle efficiency decrease

    Thermal and mechanical study of niigata 6MG28BX piston engine
    (Université M’Hamed Bougara Boumerdes : Faculté de Technologie, 2017) Bourouis, Athmane; Deriche, Mohammed Amine; Djedid, Toufik(Promoteur)
    The Main objective of this study is to appreciate the material choice in the Diesel engine piston head with direct injection on the mechanical and thermal stresses.We focused our study on the 6MG28BX engine type NIIGATA.For this study,the simulation is done applying the finite elements method using ANSYS software.Then,an analysis of deformations on each material was made.The obtained results were compared to obtain the best characteristics

    Study of the mechanical behavior of single edage notched tension (SENT)
    (Université M’Hamed Bougara Boumerdes : Faculté de Technologie, 2017) Chafai, Oussama; Kaabouche, Ali; Settet, Ahmed Tidjani(Promoteur)
    In this Work,we tried to understand and estimate the composite material’s rupture and how it reacts in the presence of different fracture dimensions especially for composite materials that are made by carbon/epoxy and glass/epoxy,so we prepared specimens using this two materials then we created different crack sizes and angles in the aim to see the propagation of the cracks and deduce the displacement,the deformation and stresses.We simulated plan specimens (without crack) and specimens that gave us the weakest results using the simulation program ‘Ansys’.then we tried to compare theses experimental results with the other results that are obtained using simulation study of the critical specimens

    Study of honeycomb panels under tensile stresses and bending
    (Université M’Hamed Bougara Boumerdes : Faculté de Technologie, 2017) Djellab, Amira; Hamzaoui, Nabil; Settet, Ahmed Tidjani(Promoteur)
    In this paper,we study the stresses applied to honeycomb sandwich panels.To do this we have prepared three samples of panels with the same core and faces of different materials and these are carbon fiber fabrics and glass fibers and then applied two types of stresses:tensile and flexural.The third type,shear stress, was illustrated using ANSYS software.The results obtained allowed us to distinguish the critical zones from the stress concentrations on the sandwich panel

    Static analysis of a smart sandwich beam subject to an extension force
    (Université M’Hamed Bougara Boumerdes : Faculté de Technologie, 2017) Maghnini, Khaled; Mekiri, Abdelghani; Aghib, Salah(Promoteur)
    The Composite materials in magnetorheological elastomer (intelligent material) possess mechanical properties important.These materials are incorporated into mechanical structures such that the beams,plates and shells,these structures sandwiches in MRE are recently used in many industrial sectors because of their high flexural stiffness accompanied by strong energy dissipation.In this work we studied the static behavior of beam composed of a core in elastomer magnetorheological inserted between two skins in aluminum.To well understand the behavior of these structures there has developed a digital approach by the method of Ritz as well as a simulation by MEF under the Code of calculation ABAQUS,the results found are well face
