【 摘 要 】

In this work, a direct approach is done to predict the accurate elastic properties of particulate composites containing and fibrous composites. To predict the elastic modulus, poisson's ratio and shear modulus, the empirical formulas like rule of mixtures, Halpin T-sai equation were taken into consideration. Properties were also determined using analytical methods like Eshelby scheme, Mori-Tanaka scheme, Self-Consistent scheme and combined approach of Mori-Tanaka and Self-Consistent schemes. The predicted properties were compared with the experimental data available from literature. Simulation was carried out for aluminium alumina particulate composites and also for boron epoxy unidirectional composites. Combined approach given by Peng et al [1]. has been used and its effectiveness has been shown.
