Abstract

Abstract

Theoretical analysis of the lateral resonances in 1-3 piezocomposites with poling initial stress was conducted using the Bloch waves theory. Based on the linear piezoelectricity theory, the theoretical formulations including initial stress for the propagation of acoustic plane waves were founded. Numerical calculations were performed to study the effects of the initial stress on the lateral mode frequencies and the stop band. It is found that the lateral mode frequencies increase with the piezoelectricity of the piezocomposites, but decrease with the poling initial stress. The influence of the initial shear stress on the lateral mode frequencies is tiny, thus it can be neglected.
