Three-Dimensional axisymmetric elastic stresses in pressure vessels with torispherical drumheads (comparison of elasticity,photoelasticity,and shell theory solutions)
The three-dimensional axisymmetric boundary value problem of pressure vessels with torispherical drumheads is analysed easily and accurately by the use of the ‘indirect fictitious-boundary integral method’. The analysed configurations are similar to each other but have different thicknesses. The comparison of the resent results with photoelasticity and shell theory solutions makes it clear that the shell theory based on Love's first approximation is very reasonable. Additionally, a vessel with hemispherical drumheads with varying thickness from cylinder to head, which is noteworthy for reducing the maximum stresses in the vessel, is studied.
