Abstract

A semi-analytical approach eccentrically stiffened functionally graded (ES-FGM) truncated conical shells surrounded by an elastic medium in thermal environments is presented. Based on the classical thin shell theory with the geometrical nonlinearity in von Karman Donnell sense, the smeared stiffeners technique and Galerkin method, this paper deals with vibration and nonlinear dynamic problem. The truncated conical shells are reinforced by ring stiffeners made of full metal or full ceramic depending on situation of stiffeners at the metal-rich or ceramic-rich side of the shell respectively. In addition, the study is not only assumed that the material properties depend on environment temperature variation, but also considered the thermal stresses in the stiffeners. Numerical results are given to evaluate effects of inhomogeneous, dimensional parameters, outside stiffeners, temperatures and elastic foundations to vibration and nonlinear dynamic response of structures.
