Abstract

In this paper, the dynamics and Vibration analysis of cylindrical shells made of graphite epoxy layers with two Piezoelectric layers at both internal and external surfaces are investigated. Extraction of motion equations is based on Sanders theory for thin shells. Equations of motion, obtained by partial derivatives, are solved by fourth-order Runge– Kutta method. First, we examine a number of geometric parameters of the problem, including shell thickness, radius, length of the shell, and the angle of the fiber in the change of the fundamental frequencies. Finally, the effect of Piezoelectric parameters on the Vibrational and dynamic response of cylindrical shells has been investigated. In all cases investigated, with an increasing ratio of length to the radius, the effect of Piezoelectric coefficients has increased. The results show that among the Piezoelectric parameters, the parameter C11 has the most effect on the frequency response so that C11 has a direct relation and C12 has an inverse relationship with the natural frequency. The influence of other Piezoelectric parameters has also been evaluated in relation to this parameter in frequency response is negligible.
