    Influence of the orientation of a multiple crack in V-shape under tensile stresse
    (Université M’Hamed Bougara Boumerdes : Faculté de Technologie, 2017) Ghazli, Tarik; Mezili, Adel; Settet, Ahmed Tidjani(Promoteur)
    We studied the influence of the orientation of the crack under tensile testing of composite plates (glass / epoxy and carbon / epoxy).We four chapters. First,the definition and characteristics,the advantage and the disadvantage of the composite materials, we also spoke about the laminate and the orientation of the fibers.Second,the theories and laws of failure and fracture according to different criteria,energy criterion,Tsai_wu criterion,tsai-hill criterion.Thirdly, we experimented on fiberglass and carbon fiber reinforced epoxy matrix plates with different sizes and orientations of cracks.Finally, we made a model using the Abaqus software to compare the results Between experimental and simulation
