Notes:
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 fL1〈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. © 1995 American Institute of Physics.
