AB  - This research concerns with free vibration analysis of piezoelectric composite materials. Based on
the theory of elasticity and piezoelectricity, the governing equations of the problem were derived. Two
differential quadrature techniques are employed to reduce the problem to an eigen-value problem. That is
solved for different materials and boundary conditions. The natural frequencies of the composite are obtained.
Numerical analysis is introduced to explain influence of computational characteristics of the proposed schemes
on convergence, accuracy and efficiency of the obtained results. The obtained results agreed with the previous
analytical and numerical ones. Also, the proposed schemes record less execution time than previous ones.
Furthermore, a parametric study is introduced to investigate the influence of elastic and geometric
characteristics of the composite on the results.
