Modal analysis of cylindrical shell under excitation of the layer piezoelectric

Nowadays, obtaining the natural frequency is one of the fundamental tools ni dynamic analysis of the structures. It can be said that without considering the natural frequency, it is not possible to extract the reliable model describing the dynamic behavior of a complicated structure. Natural frequency obtained by both theory and experiment is required for most of the research activities including scientific and industrial. In addition, in recent decays, the natural frequency method is widely used in various branches of engineering and technology to solve the structural dynamic problems. The main practical applications of this method are bio-mechanic, aerospace, automobile industries, aviation industries, ship building and specifically in mechanical engineering. In this paper, at first, the governing equations of in-complete cylindrical shells in micro are determined based on Love’s theory. Moreover, determination of natural frequency by using the semi-analytical Galerkin method is addressed
