    Abstract

    A model is derived for the analysis of the dynamic behavior of 1-3 piezocomposites. Based on this model, the effective parameters and their dependence on the aspect ratio of the unit cell of a 1-3 composite, can be evaluated. From the model we show that the mechanical quality factor of a composite can be lower than that of both the ceramic and polymer. The predictions are compared with experimental results and the agreement between the two is quite satisfactory verified.
