Abstract


In this paper, the stability of cylindrical panels with circular cross section in elastic form is estimated using both analytical and Numerical methods. The Donnell equations for linear buckling of cylindrical shells are assumed and finally the equations are resulted to numerical values with the use of Galerkin method. Boundary condition in this case is such that the two curved edges are simply supported and two straight edges are free. The effects of geometrical parameters such as thickness, radius, length and central angle on buckling of cylindrical shells have been investigated both numerically and analytically. Also, the results of both methods are presented in figures.
