    Effects of Voids Shape on Mechanical Properties of Sic Particles Reinforced Aluminium Matrix Composite
    (2025) Massinissa BOUSSALEM Aziz ABBES
    In this thesis, the effect of porosity and voids shape on the mechanical behavior of the composite reinforced with Sic particles is evaluated. The small particles adhere strongly to the Aluminum, which leads to a strong reinforcing effect. As the total contact area increased, more charges were transferred to the reinforcing particles. The main objective of this work is to study the effect of porosity (1%, 2%, 3% 4% and 5%) on the mechanical behavior of a composite material with a metal Aluminium matrix reinforced by Sic particles. For this, we varied the porosity according to the volume fraction of the particles and this for three types of arrangement (square, hexagonal and random) under unidirectional tensile loading by the finite element method. The results obtained in this work show that porosity rate and voids shape have a significant effect on the properties and behavior of composites.
