Abstract. Mathematical two-level structural models of electromagnetoelasticity of composites taking into account coherences of deformation, electric and magnetic fields are developed. Results of prediction of the 21 independent constant of effective transversal-isotropic piezoelectromagnetoelastic properties of the unidirectional fibrous composite PVF/ferrite are presented on the basis of the solution of the boundary-value problem of electromagnetoelasticity; new decisions for singular components of the second derivative Green functions for homogeneous transversal-isotropic  piezoelectromagnetoelastic medium are used.

Key words: piezocomposite, boundary-value problem of electromagnetoelasticity, effective properties.
