OICC Press Journal of Solid Mechanics 2008-7683 9 5 2017 12 30 Non-Linear Analysis of Asymmetrical Eccentrically Stiffened FGM Cylindrical Shells with Non-Linear Elastic Foundation 849 864 EN A.R Shaterzadeh Faculty of Mechanical Engineering, Shahrood University of Technology, Shahrood, Iran K Foroutan Faculty of Mechanical Engineering, Shahrood University of Technology, Shahrood, Iran Journal Article 2017 12 30 In this paper, semi-analytical method for asymmetrical eccentrically stiffened FGM cylindrical shells under external pressure and surrounded by a linear and non-linear elastic foundation is presented. The proposed linear model is based on two parameter elastic foundation Winkler and Pasternak. According to the von Karman nonlinear equations and the classical plate theory of shells, strain-displacement relations are obtained. The smeared stiffeners technique and Galerkin method, used for solving nonlinear problem. To finding the nonlinear dynamic response of fourth order Runge-Kutta method is used. The effect of parameters asymmetrical eccentrically stiffened on the nonlinear dynamic buckling response of FGM cylindrical shells have been investigated.
