• Functionally graded composite materials often possess variations in constituent volume fractions across the material which lead to a variety of microstructures. Many micromechanical models have been used to relate the effective properties of these materials to volume fraction distributions. Herein, several of these models are examined and subjected to simple tests in order to determine their validity over this wide range of application. The self-consistent method surfaces as an attractive method that provides good estimates at minimal effort with no empirical fitting parameters. Using this method, it is shown that certain assumed property distributions presented in the literature must be used with care as they are not physically realizable for certain material combinations.
