Electromechanical analysis of piezoelectric laminated composite beams

Abstract

This work demonstrates the electromechanical behavior of piezoelectric laminated composite beams using the differential quadrature method (DQM). The Chebyshev-Gauss-Lobatto sample point equation is used to select the sample points. The electromechanical responses of piezoelectric laminated composite beams with various boundary conditions are determined. The transient responses of the derived systems are calculated using the Wilson-method. In this approach, only nine sample points are required to obtain convergence. Numerical results indicate that the DQM is valid for a piezoelectric laminated composite beam formulation.
