New improved analytical solutions are obtained for tensors of effective pyro-electro-magneto-elastic properties of a piezoactive composite at initial stress-strain state (resulting from initial loading) that account for real two-point correlation functions of an irregular quasi-periodic random structure. The calculations of effective coefficients of electromagnetic and magnetoelectric coupling of the transversal isotropic unidirectional fibrous composite “PZT-4/ferrite” with an axisymmetric tensor of initial strain of the composite are presented. An increase in the absolute values of the effective coefficients is observed at negative (compressive) values of the initial strain tensor components of the composite.
