Abstract

In this article, the buckling load of an axisymmetric cylindrical shell with a variable
thickness is determined analytically by using the perturbation method. The loading is axial and the
material properties are defined by the Hooke’s law. The displacement field is predicted by using the
first order shear deformation theory and the nonlinear von-Karman relations are used for the kinematic
description of the shell. The stability equations, which are the system of nonlinear differential equations
with variable coefficients, are derived by the virtual work principle and are solved using the perturbation
technique. Also, the buckling load is determined by using the finite element method and it is compared
with the analytical solution results, the classical shell theory, and other references. The effects of linear
and nonlinear shell profiles variation on the axial buckling load are investigated. Also, we studied the
effects of geometric parameters on the buckling load results. The results show that the first order shear
deformation theory is more useful for buckling load determination of thicker shells.
