- W4250489333 abstract "In this paper we study from both theoretical and numerical points of view the problem of design and optimization of functionally graded piezoelectric material (FGPM) transducers. The governing equations for FGPM are solved using numerical scheme based on the polynomial approach. The lowest frequencies for circular and rectangular rings with different radius-to-thickness ratios are calculated to study the guided wave characteristics. It is assumed that elastic stiffnesses,piezoelectric constants and dielectric permitivities of FGPM vary in an arbitrary way inside a structure. The fundamental mode starts propagating at the phase speed that is determined numerically. Finally, two-dimensional numerical simulations are performed for various parameters to control the accuracy of the solution." @default.
