A simple analytical model based on equivalent layered approach is developed to evaluate the effective properties of magneto-electro-elastic (MEE) composites where fibers are active to electrical and magnetic domains. Although the fiber and matrix phases do not exhibit any magneto-electric coupling phenomena, the resulting MEE composite has an effective non-zero magneto-electric response. A parametric study is conducted to investigate the effects of variations in the characteristics behavior of the fiber phase on the overall magneto-electro-elastic behavior of multiferroic composite. Theoretical predictions show that the effective magneto-electric coupling constants are maximum when the piezoelectric and piezomagnetic fibers share equal volume fraction. The simulated results based on the proposed model is compared with the other models (Mori-Tanaka and finite element methods) from the literature for material coefficients [1]. The comparison shows that the model calculations are in reasonable agreement with other proposed models.
