Mori-Tanaka experimental-analytical model for predicting engineering elastic moduli of composite materials

An experimental-analytical model of homogenised elastic moduli of matrix composites has been developed based on the Mori-Tanaka analytical model. The fitting parameter of the model is the ratio of the constrained strains of the experimental sample matrix and the model composite and is determined by one experimental point for the basic composition of the composite. A linear dependence of the fitting parameter on the volume fraction of inclusions is used for composites of arbitrary composition. Good agreement is obtained between the calculation results and experimental data for isotropic and transversally isotropic composites.

Automated summary

This study developed an experimental-analytical model for the homogenized elastic moduli of matrix composites based on the Mori-Tanaka analytical model. The model's fitting parameter was determined by comparing the constrained strains of the experimental sample matrix and the model composite, and a linear relationship between the fitting parameter and the volume fraction of inclusions was used for composites of arbitrary composition. The calculation results showed good agreement with experimental data for isotropic and transversally isotropic composites.
