Abstract

Abstract

In this paper, the nonlinear axial symmetric deformation problem of nonhomogeneous ring-and stringer-stiffened shells is first solved by the exact analytic method.An analytic expression of displacements and stress resultants is obtained and its convergence is proved.Displacements and stress resultants converge to exact solution uniformly.Finally, it is only necessary to solve a system of linear algebraic equations with two unknowns.Four numerical examples are given at the end of the paper which indicate that satisfactory results can be obtained by the exact analytic method.
