Using asymptotic homogenization, we derive the local problems and the
corresponding homogenized coefficients of periodic thermomagnetoelectroelastic
heterogeneous media. The theory is applied to obtain analytical expressions for all
effective properties of an important class of periodic multilaminated composites.
Universal relations involving homogenized thermal coefficients of two-phase
laminated and fibrous piezoelectric/piezomagnetic periodic composites, with
transversely isotropic constituents, are obtained. Theoretical evidence is shown for
the existence of pyroelectric and pyromagnetic effects even if neither phase
exhibits them. Numerical calculations and comparisons with others theories are
included.
