The stress analysis of spherical shells subjected to internal pressures, using energy methods is presented in this paper.
The performance of the Ritz method was compared with a finite element method using a curvilinear element, for axisymmetric loads.
It is shown that the F.B.M gives superiors results, particularly when the shell is supported elastically.
The analysis was performed for different support conditions and shells with non-uniform thickness. Several numerical results were collected in order to compare the relative advantages of the flexibility of the elastic foundation, the flexibility of the shell and the location of the clamped edge along the meridian.
