A piezoelectric strip with finite width and thickness is placed on top of an isotropic elastic half-space. Acoustical field can be excited when a voltage is across the piezoelectric strip. An analytical method is presented to calculate the acoustical field by the dynamics characteristics of the piezoelectric strip. Considering the piezoelectric strip as an anisotropic material of the 6 mm-type crystal system, we study the two-dimensional P-SV acoustical fields inside the piezoelectric strip and the isotropic half-space. The displacement and stress distributions are analysed thoroughly. The effects of the width and thickness of the piezoelectric strip and other parameters on the acoustical field are also analysed.
