    Abstract

    The dynamic behaviors of periodic piezoceramic-polymer composite plates, especially the effect of the finite thickness on the strain distributions and resonant modes, are studied theoretically. It is found that as long as f L1<ft1, where fL1 and ft1are the thickness and first piezoelectric active stop band-edge mode frequencies, there exists a frequency f1 near fL1at which the polymer and ceramic vibrate in phase with equal amplitude in the x3 direction. The effect of the thickness of a composite plate is to change the bandwidth in which the two vibrate in unison. It is also found that due to the finite thickness effect a series of piezoelectric active modes at frequencies near and above ft1may be excited.
