Abstract EN
An efficient spectral element (SE) model for static and dynamic analysis of a piezoelectric bimorph is proposed.
It combines an equivalent single layer (ESL) model for the mechanical displacement field with a sublayer approximation for the electric potential.
The 2D Gauss-Lobatto-Legendre (GLL) shape functions are used to discretize the displacements and then the governing equation of motion is derived following the standard SE method procedure.
It is shown numerically that the present SE model can well predict both the global and local responses such as mechanical displacements, natural frequencies, and the electric potentials across the bimorph thickness.
In the case of bimorph sensor application, it is revealed that the distribution of the induced electric potential across the thickness does not affect the global natural frequencies much.
Furthermore, the effects of the order of Legendre polynomial and the mesh size on the convergence rate are investigated.
Comparison of the present results for a bimorph sensor with those from 3D finite element (FE) simulations establishes that the present SE model is accurate, robust, and computationally efficient.
