摘要: Abstract A theory is developed to analyze the internal fields in heterogeneous piezoelectric solids. It used derive expressions for mean values and variations of due external loading eigenfields. The general applicable both polycrystalline ceramics as well matrix-based composites. After development, applied multiphase composites, explicit relations are obtained two-phase Exact connections established between effective thermal properties electroelastic moduli, these agree with previous results Benveniste [3] Dunn [15] by two different approaches. stored enthalpy solid also expressed an function thermoelectroelastic properties. Finally, demonstrate applicability theory, numerical average field presented a composite consisting continuous fibers embedded polymer matrix.
