TY - EJOU AU - Wu, Kuang-Chong AU - Chen, Shyh-Haur TI - Two Dimensional Dynamic Green's Functions for Piezoelectric Materials T2 - Computer Modeling in Engineering \& Sciences PY - 2007 VL - 20 IS - 3 SN - 1526-1506 AB - A formulation for two-dimensional self-similar anisotropic elastodyamics problems is generalized to piezoelectric materials. In the formulation the general solution of the displacements is expressed in terms of the eigenvalues and eigenvectors of a related eight-dimensional eigenvalue problem. The present formulation can be used to derive analytic solutions directly without the need of performing integral transforms as required in Cagniard-de Hoop method. The method is applied to derive explicit dynamic Green's functions. Some analytic results for hexagonal 6mm materials are also derived. Numerical examples for the quartz are illustrated.
