Abstract

The aim of this paper is investigation of progressive damage in a metal matrix composite lamina usingcoupling of micromechanical method and CONTINUUM DAMAGE MECHANICS viewpoint. Themicromechanical method is a representative volume element- based method known simplified unit cellmethod which possesses the capability of investigating progressive damage and plastic behavior in therepresentative volume elements. The studied damage is isotropic and anisotropic based on continuumdamage mechanics viewpoint. Composite system under investigation is Carbon/Aluminum composite.The matrix behavior is considered as isotropic and elastoplastic and the fiber behavior is transverselyisotropic and elastic. The fiber arrangement within the matrix is regular. The matrix elastoplasticbehavior model is included as bi-linear behavior and solution method is successive approximationmethod. According to available previous studies, Silicon-carbide/Titanium composite system is notedfor validation and comparison with experimental data. Also, the effect of fiber volume fraction on thedamage progression routine is studied. The results show that by increasing the longitudinal andtransverse loadings, the damage variable grows the fiber direction and perpendicular to the fiberdirection and the axial and transverse Young's modulus decrease subsequently. Also, the results provethat in longitudinal loading, considering ANISOTROPIC DAMAGE, damage progression in the fiber directionis more than its growth, perpendicular to the fiber direction. Whereas, under transverse loading, damagegrowth in perpendicular to the fiber direction is faster.
