Abstract: The effective medium approach is one of the common micromechanical methods, which can be utilized to predict the material's effective properties and set up the quantitative relationship between the material's microstructures and macroscopic properties.It is helpful and meaningful for the new material design and reducing the (experimental) workload to use these micromechanical estimations of the material's properties.However, the calculation accuracy will decline when the effective medium method is adopted to estimate the effective properties of the composite with high volume fraction of inclusions.Therefore, in this paper the two-phase composite is taken as the example firstly and the strain of the reference medium is assumed to be the product of the average strain of the matrix and a modifying tensor.Then the expressions of the effective modulus are derived with the proposed reference medium.What's more, the solutions for modifying tensor are reached by using the achievement we obtained recently.Further, through optimizing the reference medium repeatedly, with the help of multi-level homogenization scheme, the proposed modified method is extended to predict the properties of the multiphase composite with many types of inclusions.To verify our proposed framework, the predictions are compared with the experimental data and the results of existing models.The comparisons show that the estimations of the presented method are more reasonable and acceptable.When the volume fraction of inclusions is higher, the calculation accuracy of the presented method in this paper is better than those of the existing effective medium methods.
