A review of particulate reinforcement effects on lts MMcs deformation behaviour with modelling techniques
Abstract:
In this paper, publication related to the influences of the various reinforcement factors, in particular, of particulate-reinforced metalmatrix composites (PRMMCs), such as, its shape, size, volume fraction, distribution and orientation, on the deformation are reviewed. The importance of the reinforcement-matrix interface is also noted. Micromechanical finite element (FE) modelling techniques using unit cells employed for investigation these effects on the behaviour of such composites during deformation are surveyed. It has been found that the addition of rigid reinforcing particles within monolithic metalalloys improves their strength and stiffness, but the ductility is reduced. The reinforcement also introduces inhomogeneity to the metal alloy, thus causing highly localized stress and strain fields to be set up during mechanical loading, influenced its factors of reinforcement. for PRMMCs, the effect of reinforcement clustering does not play a significant role in influencing the predicted strenght and ductility, especially at low reinforcement volume fractions. For the viewpoint of numerical analyses, although full yhree-dimensional formulation can provide the most accurate method for the modelling of the unit cell, but the perdictions obtained by use of two-dimensional analysis, are in reasonable qualitative agreement whit the experimental data
