Electromechanical properties of continuous fibre-reinforced piezoelectric composites

The objective of this paper is to present analytical expressions of the basic effective constants (for transducer applications) of fibrous piezoelectric composites with a periodic structure. These expressions were obtained on the basis of the asymptotic averaging method, following the same procedure used in 1] for the purely elastic case. The averaged electromechanical properties for these piezocomposites can be calculated from the above formulas. The results obtained from the theoretical predictions with the use of homogenization method show good agreement with the existing experimental results.Published in Mekhanika Kompozitnykh Materialov, Vol. 33, No. 5, pp. 670–680, September–October, 1997.
