Abstract
Piezoelectric coefficients hij characterise a link between an external mechanical strain applied to a sample and an electric field caused by the direct piezoelectric effect. At the converse piezoelectric effect, the piezoelectric coefficients hij characterise the link between a mechanical stress in the sample and electric displacement. Examples of the volume-fraction behaviour of the effective piezoelectric coefficients and the piezoelectric sensitivity associated with are analysed for the 2–2-type, 1–3-type and 0–3-type composites based on ferroelectrics. Relations between the piezoelectric coefficients and and some cases of the large anisotropy of are discussed for some composites.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
