Piezoelectric Response of Porous Ceramic and Composite Materials Based on (Pb, Zr)TiO3, ceramics can be described on the basis of averaging procedures similar to those suitable for the piezo-active composites. Following this principle, we will consider piezoelectric performance and features of the porous ceramics and composites as two groups of related heterogeneous materials.

Effective Electromechanical Properties in Piezo-composites, displacement or polarisation) is called the . or, more exactly, the .. At a later date, it was experimentally established that the . is also observed in acentric single crystals in that an external electric field generates a mechanical response, ., a stress or strain of the sample , similar to the electrostriction of dielectrics .

Comparison of Results on Two-component Piezo-composites,erties . Methods based on direct averaging of the properties over a macroscopic volume (analytical methods and FEM), methods based on regularisation of structure, stochastic differential equations or virial expansion, as well as a self-consistent method are often applied to determine the ef

Conclusions, specific volume-fraction ranges. These properties have been determined for specific composite architectures, connectivity and components. In a number of cases, conventional ferroelectric ceramic / polymer composites with 1–3, 2–2 or 0–3 connectivity have electromechanical properties that can be fur
