Abstract
A piezoelectric strip with finite width and thickness is placed on topof an isotropic elastic half-space. Acoustical field can be excitedwhen a voltage is across the piezoelectric strip. An analyticalmethod is presented to calculate the acoustical field by the dynamicscharacteristics of the piezoelectric strip. Considering thepiezoelectric strip as an anisotropic material of the 6 mm-typecrystal system, we study the two-dimensional P-SV acoustical fieldsinside the piezoelectric strip and the isotropic half-space. Thedisplacement and stress distributions are analysed thoroughly. Theeffects of the width and thickness of the piezoelectric strip and otherparameters on the acoustical field are also analysed.
