چکیده مقاله:
The eccentrically stiffened (ES) cylindrical shells are one of the most important structures in aerospace industries. In this paper, semi-analytical method for eccentrically stiffened functionally graded (FG) cylindrical shells under internal pressure and surrounded by an elastic foundation is presented and material properties are dependent to the temperature. The proposed model is based on two parameter elastic foundation Winkler and Pasternak. According to the Von Karman nonlinear equations and the classical plate theory (CPT), strain displacement relations are obtained. The smeared stiffeners technique and Galerkin method, used for solving nonlinear dynamic problem. The nonlinear dynamic response is obtained from fourth order Runge-Kutta method. The effect of parameters eccentrically stiffened and excitation force on the curve frequency-amplitude of nonlinear vibration and the effect of damping on the nonlinear dynamic response of cylindrical shells FGM have been investigated. The natural frequency is analyzed, too
